<p>A cookie is a small amount of information on your computer that is used by
some websites. For a brief overview, see
<a href="privacy_help.xhtml#what_are_cookies_and_how_do_they_work">What Are
Cookies and How Do They Work?</a></p>
<p>Before loading a web page that uses cookies, your browser handles the
page's cookies by doing two things:</p>
<ul>
<li>Accepts or rejects any requests by the website to <strong>set</strong>
(store) one or more cookies on your computer.</li>
<li>Accepts or rejects any requests by the website to <strong>read</strong>
cookies it previously stored on your computer. A website can't
actually read cookies or any other data on your computer—instead,
your browser gets the cookies and sends them back to the website.</li>

Allow, Allow for Session, or Deny the cookie.</p>
<p>Other dialog options:</p>
<ul>
<li><strong>Use my choice for all cookies from this website</strong>:
If you check this option, you will not be warned the next time
that website tries to set or modify a cookie, and your <q>allow</q> or
<q>deny</q> response will still be in effect.</li>
<li><strong>Show Details</strong>/<strong>Hide Details</strong>:
Click the button to show or hide <a href="#viewing_cookies">detailed
information</a> of the cookie.</li>

<h2 id="cookies">Privacy & Security Preferences - Cookies</h2>
<p>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:</p>
<ol>
<li>Open the <span class="mac">&brandShortName;</span>
<span class="noMac">Edit</span> menu and choose Preferences.</li>
<li>Under the Privacy & Security category, click Cookies. (If no
subcategories are visible, double-click Privacy & Security to expand
the list.)</li>
</ol>
<p>Cookies help websites 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
<a href="privacy_help.xhtml#what_are_cookies_and_how_do_they_work">What Are
Cookies and How Do They Work?</a></p>
<p>You can select one of these options:</p>
<ul>
<li><strong>Block cookies</strong>: Select this option to refuse all
cookies.</li>
<li><strong>Allow cookies for the originating website only</strong>: Select
this option if you don't want to accept or return
<a href="privacy_help.xhtml#what_are_third-party_cookies">foreign
cookies</a>.</li>
<li><strong>Allow all cookies</strong>: This is the default option. Select
this option to permit all websites not explicitly blocked to set cookies on
your computer.</li>
</ul>
<p><strong>Note</strong>: Blocking cookies does not remove old cookies. By
blocking cookies you only block websites from setting new cookies, and old
cookies will still be sent to websites. To completely block a website from
receiving old cookies, you need to <a href="#removing_cookies">remove its
cookies</a>.
</p>
<p><strong>Note</strong>: <a href="#cookie_sites">Per-website cookie permission</a>
supersedes default cookie setting. For example, if you allow a website to set
cookies, the website can set cookies even if you choose <q>Block cookies</q>.
</p>
<p>If you allow cookies or do not change the default setting, you can also
select the following preferences:</p>
<ul>
<li><strong>Accept cookies normally</strong>: Select this
if you want websites to set or modify cookies without restrictions.</li>
<li><strong>Accept for current session only</strong>: Select this to delete
the cookie the next time you exit your browser.</li>
<li><strong>Accept cookies for [__] days</strong>: Select this if you
want to limit the length of time any cookie can remain on your computer,
then type the number of days.</li>
<li><strong>Ask for each cookie</strong>: Select this if you want
Cookie Manager to warn you each time a website is about to store a cookie.
In addition, you can choose <strong>except for session cookies</strong>: so
that &brandShortName; will not warn you if the website is setting cookies
which will be deleted when you exit your browser.</li>
</ul>
<p>You can also get more information about your stored cookies:</p>
<ul>
<li><strong>Cookie Manager</strong>: Click this button to view
information about the cookies currently stored on your computer and which
websites are allowed to set them.</li>
</ul>
<h2 id="stored_cookies">Stored Cookies</h2>
<p>This section describes how to use the Stored Cookies tab of the Cookie
Manager. If you're not already viewing it, follow these steps:</p>
<ol>
<li>Open the Tools menu and choose Cookie Manager.</li>
<li>Choose Manage Stored Cookies from the submenu. The Cookie Manager window
opens with a list of all the cookies stored on your computer.</li>
</ol>
<p>The Stored Cookies tab lists all the cookies stored on your computer, the
websites they belong to, and their current status.</p>
<p>When you select a cookie in this list, the following information about that
cookie appears in the bottom portion of the tab:</p>
<table class="defaultTable">
<thead>
<tr>
<th>Item</th>
<th>Explanation</th>
</tr>
</thead>
<tbody class="tbody-default">
<tr>
<td>Name</td>
<td>The name assigned to the cookie by its originator.</td>
</tr>
<tr>
<td>Information</td>
<td>A string of characters containing the information a website tracks
for you. It might contain a user key or name by which you are
identified to the website, information about your interests, and so
forth.</td>
</tr>
<tr>
<td>Host or domain</td>
<td>Provides the name of the cookie's host or domain.
<p>A <strong>host</strong> cookie is sent back, during subsequent
visits, only to the <a href="glossary.xhtml#server">server</a> that
set it.</p>
<p>A <strong>domain</strong> cookie is sent back to any website
that's in the same domain as the website that set it. A
website'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.</p>

<h1 id="using_the_password_manager">Using the Password Manager</h1>
<p>Many websites require you to type a user name and password before you can
enter the website. For instance, personalized pages and websites containing
your financial information usually require you to log in.</p>
<p>The user name and password you use at a particular website can be read by the
site's administrator. Potentially, that person could then attempt to log
into other websites 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
website with which you register.</p>
<p>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 websites.</p>

<h2 id="using_password_manager_to_remember_user_names_and_passwords">Using
Password Manager to Remember User Names and Passwords</h2>
<p>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.</p>
<p>For example, after you log onto a website from a page that requests a user
name and password, a dialog box appears asking, <q>Do you want Password
Manager to remember this logon?</q> When you see this dialog box, you can
click one of the following buttons:</p>
<ul>
<li><strong>Yes</strong>: The next time you return to the website you'll
see that your user name and password are already filled in. All you have to
do is click the Login button (or equivalent) to send them to the
server.</li>
<li><strong>Never for this site</strong>: Password Manager will not ask in
the future if you want to save your user name and password for that
website.</li>
<li><strong>No</strong>: Password Manager won't remember the user name
and password, but will ask again the next time you visit the website.</li>
</ul>
<p>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:</p>
<ul>
<li><strong>Use Password Manager to remember these values</strong></li>
</ul>
<p>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.</p>
<p>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 <a href="#encrypting_stored_sensitive_information">Encrypting Stored
Sensitive Information</a> for information on protecting your stored user
names and passwords with encryption technology.</p>
<p>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 website may disallow its use.</p>
<p>To check whether Password Manager is currently active, see
<a href="#turning_password_manager_on_and_off">Turning Password Manager On
and Off</a>.</p>
<p>[<a href="#using_the_password_manager">Return to beginning of

<h2 id="entering_user_names_and_passwords_automatically">Entering User Names
and Passwords Automatically</h2>
<p>There are two different ways that Password Manager can fill in user names
and passwords on your behalf:</p>
<ul>
<li>You use Password Manager to remember your user name and password for a
website (using the three-button dialog box described in
<a href=
"#using_password_manager_to_remember_user_names_and_passwords">Using
Password Manager to Remember User Names and Passwords</a>).
<p>The next time you visit the website, Password Manager automatically fills
in your user name and password on the website's log in page. You can
then click the Login button, or equivalent, to send the information to
the server.</p>
</li>
<li>You use Password Manager to remember your user name and password for an
email account, an FTP site, or in any other situation where you type login
information in a dialog box that displays a checkbox labeled <q>Use
Password Manager to remember these values</q>.
<p>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.</p>
<p>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.</p>
</li>
</ul>
<p>[<a href="#using_the_password_manager">Return to beginning of
section</a>]</p>
<h2 id="turning_password_manager_on_and_off">Turning Password Manager On and
Off</h2>
<p>Password Manager is on by default. To turn it off:</p>
<ol>
<li>Open the <span class="mac">&brandShortName;</span>
<span class="noMac">Edit</span> menu and choose Preferences.</li>
<li>Under the Privacy & Security category, click Passwords. (If no
subcategories are visible, double-click Privacy & Security to expand
the list.)</li>
<li>In the Password Manager section, deselect <q>Remember passwords</q>
to turn Password Manager off.</li>
</ol>
<p>To turn Password Manager on, follow steps 1 and 2 above, but select the
checkbox in step 3 rather than deselecting it.</p>
<p>[<a href="#using_the_password_manager">Return to beginning of
section</a>]</p>
<h2 id="viewing_and_managing_stored_passwords">Viewing and Managing Stored
Passwords</h2>
<p>To see the user names and passwords you have stored and to display a list of
websites from which logon information never is saved:</p>
<ul>
<li>Open the Tools menu, choose Password Manager, and then choose Manage
Stored Passwords from the submenu. You see the Password Manager window with
the Passwords Saved tab opened.
<ul>
<li>To see your saved passwords, click Show Passwords and confirm your
choice.</li>
<li>To hide your passwords, click Hide Passwords.</li>
<li>To remove an entry from the list, click it and then click Remove. The
next time you visit the website, you will need to enter your user name
and password again, since Password Manager will no longer have the
information.</li>
</ul>
Click the Passwords Never Saved tab to see a list of the websites for which
you instructed Password Manager never to store user names and passwords. To
remove a website from this list, click it and then click Remove. The next
time you log into the website, you can use the stored user name and
password (if available) or indicate that you want Password Manager to save
the information for that website.</li>
</ul>
<p>[<a href="#using_the_password_manager">Return to beginning of
section</a>]</p>
<h1 id="encrypting_stored_sensitive_information">Encrypting Stored Sensitive
Information</h1>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>Your decision about whether to use encryption for stored sensitive data is a
tradeoff between improved security and convenience.</p>
<p>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.</p>

</ul>
</div>
<h2 id="setting_a_master_password">Setting a Master Password</h2>
<p>To enable encryption of passwords you need to set a master password. If
your master password has not previously been set, you can set it at this
time:</p>
<ol>
<li>Open the <span class="mac">&brandShortName;</span>
<span class="noMac">Edit</span> menu and choose Preferences.</li>
<li>Under the Privacy & Security category, click Master Passwords. (If no
subcategories are visible, double-click Privacy & Security to expand

<li>In the Change Master Password section, click Change Password to open the
Change Master Password dialog box.</li>
<li>Enter your desired master password, and retype it to confirm the
spelling.</li>
<li>Click OK.</li>
</ol>
<p>Make sure your new password is difficult to guess. For some suggestions on
how to improve password security, see

<p>[<a href="#encrypting_stored_sensitive_information">Return to beginning of

<h2 id="logging_out_of_your_master_password">Logging Out of Your Master
Password</h2>
<p>Normally, you are asked for your master password once during each
&brandShortName; session during which you access any of your stored sensitive
information.</p>
<p>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 <a href="passwords_help.xhtml#master_password_timeout">Master
Password Timeout</a>.</p>
<p>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.</p>
<p>To log out of your master password:</p>
<ol>
<li>Open the Tools menu and choose Password Manager.</li>
<li>Select Log Out from the submenu.</li>

<h2 id="what_to_do_if_you_forget_your_master_password">What to Do If You Forget
Your Master Password</h2>
<p>If you forget your master password, you won't be able to access any of
the stored password it protects. Your master password is your most important
password. Make sure you remember it or record it in a safe place.</p>
<p>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
<a href="glossary.xhtml#software_security_device">Software Security
Device</a>.</p>
<p>Before taking this drastic step, read
<a href="passwords_help.xhtml#reset_master_password">Reset Master

<p>If you are sure you can't remember or retrieve your master password,
follow these instructions to reset it:</p>

<li>Open the <span class="mac">&brandShortName;</span>
<span class="noMac">Edit</span> menu and choose Preferences.</li>
<li>Under the Privacy & Security category, click Master Passwords. (If no
