To control cookies on a site-by-site basis:
Alternatively, if you have selected "Ask me before storing a cookie" in Privacy & Security Preferences - Cookies, you will be warned (while browsing) that a web site is asking to set a cookie. When you see such a warning, you can click Yes to allow or No to deny the cookie. You can also select the option for your browser to "Remember this decision."
If you select "Remember this decision", you will not be warned the next time that site tries to set or modify a cookie, and your "yes" or "no" response will still be in effect.
If you want to change a remembered response later, use Cookie Manager to edit your list of automatically stored cookies.

Many web sites develop and publish their privacy policies based on the Platform for Privacy Preferences (P3P) standard. The information that follows applies only to web sites that post a privacy policy based on the P3P standard and the browser's implementation of that standard. The browser's implementation may not be, in all cases, identical to the standard published by the World Wide Web Consortium.
A web site's P3P privacy policy describes, in a standardized way, what kind of information the site collects, to whom it gives that information, and how it uses the information. For information about viewing a web site's privacy policy, see Viewing Privacy Policies.
Navigator's implementation of the P3P standard defines three levels of privacy: low, medium, and high (the default is medium). You can select one of these predefined privacy levels, or you can specify your own custom privacy settings in detail. Once you have set your preferred privacy level, your browser can compare your preferences with the web site's P3P policy (if any) and accept or reject cookies accordingly.
For example, your privacy settings may require the browser to reject cookies that collect personal information without informing you. Alternatively, you can adjust your privacy settings so that the browser simply warns you when a cookie is used in this way, while allowing the action to take place.
To control the privacy settings you want your browser to enforce for all web sites:
Your browser handles cookies according to the settings you select. If you do not select a preferred setting, the browser defaults to medium. The low, medium, and high options are predefined by &brandShortName;. For more information about these predefined options, see Privacy Settings.
When the "custom" option is selected, you can specify your own privacy settings in detail. Depending on the P3P policy of the site setting the cookie, and depending on whether or not the site setting the cookie is the one you are viewing, you can select whether you want the Cookie Manager to accept the cookie, reject it, accept it just for the current session (that is, until you exit the browser), or flag it.
If you choose Reject, Flag, or Session for a given category of cookies, the Cookie Manager displays the cookie notification icon near the lower-right corner of the browser window whenever a web site that fits the category sets a cookie. When this icon is displayed, you can click it to get information about the affected cookies.
"First party cookies" are cookies set by the site you are visiting. "Third-party cookies", also known as foreign cookies, are set by sites other than the one you are viewing.
For more details, see Privacy Settings.

This section describes how to set your Cookies preferences and control other aspects of cookie handling.
For step-by-step descriptions of various tasks related to cookies, see Using the Cookie Manager.
In this section: |
Your browser is set by default to accept all cookies. This section describes how to use the Cookies preferences panel to change that setting. If you're not already viewing it, follow these steps:
Cookies help web sites keep track of information for you, such as the contents of your on-line shopping cart or which cities' weather you want to know about. For a brief overview, see What Are Cookies and How Do They Work?
You can select one of these options:
Disable cookies: Select this option to refuse all cookies.
Note: If you select this option and later choose to disable all cookies, you may still have old cookies stored on your computer (though no new ones will be set).
If you enable cookies or do not change the default setting, you can also select the following preferences:
You can also get more information about your stored cookies:
This section describes how to use the Stored Cookies tab of the Cookie Manager. If you're not already viewing it, follow these steps:
The Stored Cookies tab lists all the cookies stored on your computer, the sites they belong to, and their current status.
If you can't see the Status column, click the icon in the upper-right corner of the table and select Status. This column indicates which cookies have been flagged or accepted according to your Privacy Settings.
When you select a cookie in this list, the following information
about that cookie appears in the bottom portion of the tab:
Item | Explanation |
Name | The name assigned to the cookie by its originator. |
Information | A string of characters containing the information a web site tracks for you. It might contain a user key or name by which you are identified to the web site, information about your interests, and so forth. |
Host or domain | Provides the name of the cookie's host or domain.
A host cookie is sent back, during subsequent visits, only to the server that set it. A domain cookie is sent back to any site that's in the same domain as the site that set it. A site's domain is the part of its URL that contains the name of an organization, business, or school—such as netscape.com or washington.org. |
Path | The file pathway. This is provided only if the cookie should be sent back to all URLs that are on that path or lower. For example, http://a.b/x/y/z.html means that the cookie can also be set for path x/. |
Server Secure | When this field is "Yes" it means that the browser checks the connection whenever the server asks for a cookie and will not send it unless the connection is encrypted (HTTPS). |
Expires | The date and time at which the cookie will be deactivated. The browser regularly removes expired cookies from your computer. |
Policy | The type of privacy policy information that the site has explicitly declared that it publishes. (Even if this field is blank, it may still be possible to view the site's policy; see Viewing Privacy Policies for details.) |
To remove cookies, click one of these buttons:
Select this checkbox to prevent the cookies you remove from being added back into the list later:
Even if you remove cookies now, you will reacquire those same cookies the next time you return to the web site. To prevent that from happening, select this checkbox. When this checkbox is selected, web sites for the cookies that you are removing are added to the list of sites whose cookies will automatically be rejected.
You must click OK for your changes to take effect.
This section describes how to use the Cookie Sites tab of the Cookie Manager. If you're not already viewing it, follow these steps:
If the "Ask me before storing a cookie" option is selected in Privacy & Security Preferences - Cookies, you will be warned (while browsing) each time a web site requests permission to set a cookie. The warning allows you to accept or deny the cookie. The warning also allows you to select an option for your browser to "Remember this decision."
The Cookie Sites tab of the Cookie Manager lists the sites for which your decisions have been remembered, and what your decisions were. It also allows you to remove sites from the list, so that the Cookie Manager no longer remembers your decisions about them:
Once you've removed a site from this list, Cookie Manager remembers nothing about it. If the "Ask me before storing a cookie" option is selected in the Cookies preferences panel, you will again be warned when the web site you removed from this list requests permission to set a cookie.
This section describes how to use the Privacy Settings window. If you're not already viewing it, follow these steps:
For more information about using privacy settings, see Setting Privacy Levels.
In this section: |
The level of privacy you set here determines how your browser treats cookies according to privacy policies based on the P3P standard that published by some web sites and on the settings displayed under Cookie Acceptance Policy for first-party and third-party cookies.
"First party cookies" are cookies set by the site you are visiting. "Third-party cookies", also known as foreign cookies, are set by sites other than the one you are viewing.
You can select one of the following privacy levels:
When this setting is selected, the browser accepts all third-party cookies, but flags third-party cookies from sites that indicate they may collect personally identifiable information without your consent. Flagged cookies are listed as "flagged" in the status column of the Cookie Manager's Stored Cookies tab.
When a cookie is first flagged, the Cookie Manager displays the cookie notification icon near the lower-right corner of the browser window (if it's not already present). You can click the cookie notification icon to see more detailed information about the flagged cookies.
To see the exact effect of each privacy-level setting, select it and then examine the Cookie Acceptance Policy settings.
If you select the custom option in the top portion of the Privacy Settings dialog box, you can choose one of four settings from the drop-down list in each of the eight categories shown in the bottom portion. These settings cause Cookie Manager to perform the following actions:
The cookie notification icon appears near the lower-right corner of the browser window. You can click it to get information about the affected cookies or modify your privacy settings.
Web sites are classified in four categories for each of the two types (first-party and third-party) of cookies:
The cookie notification icon is displayed in the status bar near the lower-right corner of the browser window. It appears when a web site has used a cookie in a way that requires you to be notified according to your current Privacy Settings.
This section describes how to use the Cookie Notification dialog box, which appears when you click the Cookie Notification icon. You can take the following actions from this dialog box:
For more information about using privacy settings, see Setting Privacy Levels.
Many web sites require you to type a user name and password before you can enter the site. For instance, personalized pages and web sites containing your financial information usually require you to log in.
The user name and password you use at a particular site can be read by the site's administrator. Potentially, that person could then attempt to log into other sites where you may have used the same user name and password. If this concerns you, you may wish to use a different password at every site with which you register.
Password Manager can help you remember some or all of your names and passwords by storing them on your computer's hard disk, and entering them for you automatically when you visit such sites.
In this section: Using Password Manager to Remember User Names and Passwords Entering User Names and Passwords Automatically Turning Password Manager On and Off |
When Password Manager is active (as it is by default), it gives you an opportunity to save user names and passwords on your hard drive that you enter while using the Internet.
For example, after you log onto a web site from a page that requests a user name and password, a dialog box appears asking, "Do you want Password Manager to remember this logon?" When you see this dialog box, you can click one of the following buttons:
Similarly, when you log onto an email account or an FTP site, or perform any other action that requires the browser itself to display a special dialog box for your login information, you can select this option in the dialog box:
The next time you check your email or perform other tasks that require a password only, the password will be submitted directly without any futher action on your part. For tasks that require you to enter both a user name and password, you need to click a Login button or equivalent after Password Manager fills in the information.
Password Manager saves your user names and passwords on your own computer in a file that's difficult, but not impossible, for an intruder to read. See Encrypting Stored Sensitive Information for information on protecting your stored user names and passwords with encryption technology.
If the Password Manager dialog box described above does not appear when you click Submit after typing your user name and password, Password Manager may be turned off or the web site may disallow its use.
To check whether Password Manager is currently active, see Turning Password Manager On and Off.
[ Return to beginning of section ]
There are two different ways that Password Manager can fill in user names and passwords on your behalf:
The next time you visit the site, Password Manager automatically fills in your user name and password on the site's log in page. You can then click the Login button, or equivalent, to send the information to the server.
In most cases, the next time you attempt to access that server, Password Manager automatically fills in your user name and password in the same dialog box. You can then click OK to send the information to the server.
In some cases, such as when you open your email account, &brandShortName; needs to send only the password to the server, and does so immediately without displaying the dialog box or requiring any further action on your part.

Password Manager is on by default. To turn it off:
To turn Password Manager on, follow steps 1 and 2 above, but select the checkbox in step 3 rather than deselecting it.

Many web pages contain forms for you to fill out—order forms for online shopping, information databases, and so forth.
Form Manager can save the personal data you enter into online forms, such as your name, address, phone, credit card numbers, and so on. This information is stored on your hard drive. Then, when a web site presents you with a form, Form Manager can fill it in automatically.
In this section: Filling Out Forms Automatically Turning Off Form Manager Notification |
By default, when you fill out an online form and click Submit, Form Manager detects the form and displays a dialog box asking if you want to save the personal data you just entered. Soon, Form Manager will have enough data to begin filling out forms automatically.
There are two ways to save personal data:
Note that Form Manager prompts you only if its automatic notification feature is turned on. (This feature is turned on by default.) For details, see Turning Off Form Manager Notification.
When Form Manager asks if you want to save values that you've entered in a form (the first method described above), it gives you three options:
You may want to do this if you want to ensure that you'll always have to enter sensitive information manually at a particular site. You can change your mind later if you like; for details, see Editing Stored Site Information.
Form Manager stores your personal data on your own computer in a file that's difficult, but not impossible, for an intruder to read. See Encrypting Stored Sensitive Information for information on protecting your information with encryption technology.
[ Return to beginning of section ]
You can use the Form Manager to fill out forms automatically in two ways: either one field at a time, or multiple fields at once. In both cases, the information is not actually sent to the site until you click the Submit button or perform some similar action.
To fill out a single field automatically in an online form, double-click in the field. If Form Manager has stored the data for that field, it will fill it in. You can edit the filled-in data if necessary.
To fill out multiple fields in an online form all at once:
Note that the Fill in Form menu item won't be accessible if the Form Manager hasn't yet stored any relevant information.
Important: You can also choose to bypass this dialog box in the future. However, if you bypass this screen, you risk filling in personal information (such as your credit card number) inadvertently. For details, see below.
The form is now filed in with the saved information. You may still need to provide some additional information that the Form Manager does not have available. The information is not actually sent to the site until you click Submit or perform some similar action.
In addition to providing a convenient way to confirm saved data and fill in a form all at once, the Prefill Form Data dialog box is useful for two reasons:
For example, it's possible for a web site to hide a field on a form where you can't see it and specify that field to be a credit card number. If you prefill the form without first examining the information displayed in the Prefill Form Data dialog box, you may end up providing your credit card number to such a web site without realizing it. Prefill Form Data lets you see every value that will be provided to the site, allowing you to detect such tricks.
For a detailed description of the Prefill Form Data dialog box, see Prefill Form Data.
[ Return to beginning of section ]
Form Manager is set to prompt you to save information whenever you submit an online form that includes certain kinds of information, such as your name and address. To stop these messages from appearing on your screen:
Note that deselecting this option turns off the notification feature, but not Form Manager. The form data it may have already collected is still available.
You can still open the Edit menu and choose Save Form Info any time you want to save information from a form you've just filled in, or choose Fill in Form (or double-click each field) to fill in a form automatically.
[ Return to beginning of section ]
To examine or edit personal data that Form Manager has saved:
The Form Manager dialog box for editing data appears. Click the subcategories on the left to view or edit the corresponding data in the panel on the right. To view subcategories that aren't visible, double-click a category to expand the list.
To add information not currently included in one of the drop down lists on the right, select the blank item and start typing. Similarly, select existing text to edit or delete it.
The last category on the left side, Other Saved Information, includes panels for two special kinds of data:
[ Return to beginning of section ]
As explained in Saving Form Data, you can choose "Never for this site" when Form Manager prompts you to save data you've entered in a form. Similarly, you can choose not to display the Prefill Form Data dialog box on a site-by-site basis.
Form Manager lets you change your mind about these decisions at any time. To view site-specific information about your saved form data:
The Form Manager dialog box for managing sites appears:
To remove a site from either list and thus restore the default behavior, select the site and click Remove. For more details, see Form Manager - Sites.

When you provide personal information such as your name, phone number, or email address to a web site, or when the site collects personal information in other ways, the site can use the information for its own purposes (such as shipping you a product or customizing your browsing experience) and can potentially share it with others.
Before providing personal information on an online form, you must decide whether or not you trust the web site—just as you judge whether or not you trust a catalog company before you provide your credit card number on the company's order form.
One way to evaluate a web site's trustworthiness is to examine its published privacy policy. Web sites publish privacy statements online, and some of them publish such statements based on the Platform for Privacy Preferences (P3P) standard and the browser's implementation of that standard.
A web site's privacy policy describes what kind of information the site collects, to whom it gives that information, and how it uses the information. Web sites publish privacy policies in both human-readable form and as a file that can be interpreted by the browser according to your Privacy Settings.
To view a web site's privacy policy, browse to the site and follow these steps:
Many web pages are made up of a variety of text, images, advertisements, and other elements, some of which may be controlled by different companies.
To view the same information for any individual element of the web page:

The Form Manager window for managing sites has two tabs:
If you remove an entry from this list, Form Manager will again give you an opportunity to review form data for that site before filling it in.
If you remove an entry from this list, Form Manager will again ask whether to store form data when you submit forms at that site (assuming that the main Form Manager notification option has been selected in Privacy & Security Preferences - Forms).
Regardless of which tab you are viewing, you can remove entries from the list as follows:
See the descriptions of each tab above for the consequences of removing entries.
For step-by-step instructions on working with form data, see Using the Form Manager.
This section describes the window that normally appears when you open the Edit menu and choose Fill In Form.

If you change your mind about this decision, you can restore the Prefill Form Data window for this web site. For details, see Form Manager - Sites.
If you use Password Manager or Form Manager to save passwords and personal data, then this sensitive information is stored on your computer in a file that's difficult, but not impossible, for an intruder to read.
For example, if your computer is in an area where unauthorized people have access to it, it's possible for a determined person to read the file containing your sensitive information.
For a greater degree of security, you may want to protect the file with encryption. Encryption makes it much harder for an unauthorized person to view your stored sensitive information.
Your decision about whether to use encryption for stored sensitive data is a tradeoff between improved security and convenience.
If you use encryption, you will need to enter a master password periodically, which can be inconvenient. If you don't, it may be easier for a stranger who has access to your computer to steal your passwords.
In this section: |
To turn on encryption for your stored sensitive information:
To turn encryption off, deselect "Use encryption when storing sensitive data."
You must supply your master password when you turn encryption on or off.
[ Return to beginning of section ]
If you choose to encrypt your stored sensitive information, you'll need a master password. With encryption selected, you'll be asked for your master password at least once during a browser session in which you access any of your stored sensitive information.
If you choose encryption, but don't already have a master password, you'll be prompted to create one the first time you try to save or retrieve your sensitive information.
If your master password has not previously been set, you can set at this time:
You see the Set Master Password dialog box.
Make sure your new password is difficult to guess. For some suggestions on how to improve password security, see the online document Choosing a Good Password.
[ Return to beginning of section ]
To change your master password:
Make sure your new password is difficult to guess. For some guidelines, see the online document Choosing a Good Password.
[ Return to beginning of section ]
Normally, you are asked for your master password once during each browser session during which you access any of your stored sensitive information.
It's also possible to require that your master password be requested each time it is needed, or after a certain amount of time has passed. For details, see Master Password Timeout.
You can log out of your master password so that it must be entered again before any sensitive information can be stored or retrieved. This is useful if you are going to leave your computer unattended for a period of time.
To log out of your master password:
[ Return to beginning of section ]
If you forget your master password and you have chosen to encrypt sensitive data (see Encrypting Stored Sensitive Information), you won't be able to access any of the stored password and form data that it protects (assuming you have turned on encryption. Your master password is your most important password. Make sure you remember it or record it in a safe place.
As a last resort, it's possible to reset your master password if you are sure you can't remember it. However, resetting your master password permanently erases all the web passwords, email passwords, and form data saved on your behalf by Password Manager and Form Manager. You will also lose all your personal certificates associated with the Software Security Device.
Before taking this drastic step, read Reset Master Password.
If you are sure you can't remember or retrieve your master password, follow these instructions to reset it:
