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.
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 site tracks for you. It might contain a user key or name by which you are identified to the 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/. |
| Send For | When this field is For encrypted connections onlyit 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. |
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 site. To prevent that from happening, select this checkbox. When this checkbox is selected, sites for the cookies that you are removing are added to the list of sites whose cookies will automatically be rejected.
You must click Close 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:
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 add and remove sites from the list.
To add cookies sites manually:
To remove a cookie site:
Once you've removed a site from this list, Cookie Manager remembers
nothing about it. If the Ask for each cookie
option is selected in
the Cookies preferences panel, you will be warned when any site not in this
list requests permission to set a cookie.
Many sites require you to type a user name and password before you can enter the site. For instance, personalized pages and 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.
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 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 further 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 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.
Use Password Manager to remember these values.
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:
Remember passwordsto turn Password Manager off.
To turn Password Manager on, follow steps 1 and 2 above, but select the checkbox in step 3 rather than deselecting it.

To see the user names and passwords you have stored and to display a list of sites from which logon information never is saved:
[Return to beginning of section]
If you use Password Manager to save passwords, 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.
To turn on encryption for your stored sensitive information:
Use encryption when storing sensitive data.
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 &brandShortName; 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:
Make sure your new password is difficult to guess. For some suggestions on how to improve password security, see 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 Choosing a Good Password.
[Return to beginning of section]
Normally, you are asked for your master password once during each &brandShortName; 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 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 and email passwords, saved on your behalf by Password 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:
