Firefox 2 Beta 2 is a developer preview release of our next generation Firefox browser and it is being made available for testing purposes only. Firefox 2 Beta 2 is intended for Web application developers and our testing community. Current users of Firefox 1.x should not use Firefox 2 Beta 2 and expect all of their extensions and plugins to work properly.
These Release Notes cover what's new, download and installation instructions, known issues and frequently asked questions for the Firefox 2 Beta 2 release. Please read these notes and the bug filing instructions before reporting any bugs to Bugzilla.
Give us your feedback through this feedback form.
There is a lot in Firefox 2 Beta 2 that you can play around with and give us feedback on:
- Visual Refresh: Firefox 2's theme and user interface have been updated to improve usability without altering
the familiarity of the browsing experience. For instance, toolbar buttons now glow when you hover over them. We will continue
to improve the look and feel throughout the release candidate process.
- Built-in phishing protection: Phishing Protection warns users
when they encounter suspected Web forgeries, and offers to return the user to their home page. Phishing Protection is turned on by
default, and works by checking sites against either a local or online list of known phishing sites. This list is automatically
downloaded and regularly updated when the Phishing Protection feature is enabled. Please note that at this time we are using
a limited list to test the core Phishing Protection framework within the browser. Users are encouraged to wait until a future release
of Firefox 2 to verify the accuracy of the list of Web forgeries.
- Enhanced search capabilities: Search term suggestions will now appear as users type in the integrated search box when using
the Google, Yahoo! or Answers.com search engines. A new search engine manager makes it easier to add, remove and re-order search
engines, and users will be alerted when Firefox encounters a website that offers new search engines that the user may wish to install.
- Improved tabbed browsing: By default, Firefox will open links in new tabs instead of new windows, and each tab will now have
a close tab button. Power users who open more tabs than can fit in a single window will see arrows on the left and right side of
the tab strip that let them scroll back and forth between their tabs. The History menu will keep a list of recently closed tabs,
and a shortcut lets users quickly re-open an accidentally closed tab.
- Resuming your browsing session: The Session Restore feature restores windows, tabs, text typed in forms, and in-progress downloads
from the last user session. It will be activated automatically when installing an application update or extension, and users will be asked
if they want to resume their previous session after a system crash.
- Previewing and subscribing to Web feeds: Users can decide how to handle Web feeds (like
this one), either subscribing to them via a Web service or in a
standalone RSS reader, or adding them as Live Bookmarks. My Yahoo!, Bloglines
and Google Reader come pre-loaded as Web service options, but users can add any Web service that handles RSS feeds.
- Inline spell checking: A new built-in spell checker enables users to quickly check the spelling of text entered into Web forms
(like this one) without having to use a seperate application.
- Live Titles: When a website offers a microsummary (a regularly updated summary
of the most important information on a Web page), users can create a bookmark with a "Live Title". Compact enough to fit in the space
available to a bookmark label, they provide more useful information about pages than static page titles, and are regularly updated
with the latest information. There are several websites that can be
bookmarked with Live Titles, and even more add-ons to generate
Live Titles for other popular websites.
- Improved Add-ons manager: The new Add-ons manager improves the user interface for managing extensions and themes, combining
them both in a single tool.
several new features such as generators, iterators, array
- Extended search plugin format: The Firefox search
engine format now supports search engine plugins written in Sherlock and OpenSearch formats and allows search engines to provide
search term suggestions.
- Updates to the extension system: The extension system has been updated to provide enhanced security and to allow for easier
localization of extensions.
- Client-side session and persistent storage: New support for storing structured data on the client side, to enable better
handling of online transactions and improved performance when dealing with large amounts of data, such as documents and
mailboxes. This is based on the WHATWG specification
for client-side session and persistent storage.
- SVG text: Support for the svg:textpath specification enables SVG text to follow a curve or shape.
- New Windows installer: Based on Nullsoft Scriptable Install System, the new Windows installer resolves many long-standing issues.

Extensions and Themes
Extensions installed under Firefox 1.5 may be incompatible and/or require updates to work with Firefox 2 Beta 2. Please report any issues to the maintainer of the extension. When you install Firefox 2 Beta 2 all of your Extensions and Themes may be disabled until Firefox 2 Beta 2 determines that either a) they are compatible with the Firefox 2 Beta 2 release or b) there are newer versions available that are compatible.
This list covers some of the known problems with Firefox 2 Beta 2. Please read this before reporting any new bugs, and watch it regularly (we'll update it as new bugs are found in the release).
- Phishing Protection:
- At this time we are using a limited list to test the core Phishing Protection framework within the browser. Users are encouraged to verify that the above test links properly display a warning dialogue, but to wait until a future release of Firefox 2 to verify the accuracy of the list of Web Forgeries.
- History and Bookmarks:
- The new history and bookmark system used in Bon Echo Alpha 1 has been removed. You will need to follow these steps if you are migrating a profile from Bon Echo Alpha 1.
- When moving to Firefox 2 Beta 2 from an earlier version of Firefox, some of your Extensions and Themes may be disabled. See "Extension and Themes", above.
- Feed Preview and Subscription:
- Web based Feed Readers added by users aren't remembered in the Feeds preferences pane. This is being tracked by bug 349225.
- Spell Checking:
- Dictionaries for several locales can't be packaged with the builds, and must be manually downloaded by selecting "Add Dictionaries..." on the shortcut menu. New dictionaries are regularly being added to Mozilla Add-ons, so if you don't see the particular dictionary you need, check back later. In future releases, users will be offered the opportunity to download dictionaries the first time they run the product (see bug 349945).
- Help System:
- In some localized builds, there are several blank help pages. This is being tracked by bug 344312.
- If you obtained Firefox 2 Beta 2 through the Software Updater, you will not be able to uninstall it from the Windows Control Panel. You can manually uninstall the application by running "uninstall.exe" in the "Uninstall" folder located where Firefox 2 Beta 2 is installed. This has been fixed by bug 349551.
Mac OS X
- Users running Firefox on Mac OS X 10.3 may experience frequent crashes due to bug 345388. This was fixed after the deadline for Firefox 2 Beta 2 and will not happen in recent nightly or future builds of Firefox.
Poorly designed or incompatible Extensions can cause problems with your browser, including make it crash, slow down page display, etc. If you encounter strange problems relating to parts of the browser no longer working, the browser not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble.
Restart the browser in Safe Mode. On Windows, start using the "Safe Mode" shortcut created in your
Start menu or by running
firefox.exe -safe-mode. On Linux, start with
./firefox -safe-modeand on Mac OS X, run:
When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
If you uninstall an extension that is installed with your user profile (i.e. you installed it from a Web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart the browser once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally.
If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running Firefox with the -P command line argument, choose the "Manage Profiles" button and then choose "Create Profile...". Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file.
