What’s New in Firefox 3.6
Firefox 3.6 is built on Mozilla's Gecko 1.9.2 web rendering platform, which has been under development since early 2009 and contains many improvements for web developers, add-on developers, and users. This version is also faster and more responsive than previous versions and has been optimized to run on small device operating systems such as Maemo.
Notable Firefox 3.6 features include:
- Available in more than 70 languages - get your local version.
- Support for a new type of theme called Personas, which allow users to change Firefox's appearance with a single click.
- Protection from out-of-date plugins to keep users safer as they browse.
- Open, native video can now be displayed full screen and supports poster frames.
- The ability for web developers to indicate that scripts should run asynchronously to speed up page load times.
- Continued support for downloadable web fonts using the new WOFF font format.
- Support for new CSS attributes such as gradients, background sizing, and pointer events.
- Support for new DOM and HTML5 specifications including the Drag & Drop API and the File API, which allow for more interactive web pages.
- Changes to how third-party software can integrate with Firefox in order to prevent crashes.
Developers can find out about all the changes and new features at the Mozilla Developer Center.
Before installing, make sure your computer meets the system requirements.
Mozilla provides Firefox 3.6 for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Firefox 3.6 here. For builds for other systems and languages not provided by Mozilla, see the Contributed Builds section at the end of this document.
Please note that installing Firefox 3.6 will overwrite your existing installation of Firefox. You won’t lose any of your bookmarks or browsing history, but some of your extensions and other add-ons might not work until updates for them are made available. You can reinstall an older version later if you wish to downgrade.
You can remove Firefox 3.6 through the Control Panel in the Start Menu on Windows, by removing the Firefox application on OS X, or by removing the firefox folder on Linux.
By default, removing Firefox 3.6 won’t remove your bookmarks, web browsing history, extensions or other add-ons. This data is stored in your profile folder, which can be found by going to the Help menu and selecting Troubleshooting Information.... The button next to the Profile Directory line in Application Basics will open your profile directory in your system's file explorer.
Please note that if you keep your profile, any version of Firefox that you install after removing Firefox 3.6 will continue to use the bookmarks, web browsing history, add-ons, and other data from this profile folder.
Extensions and Themes
Extensions installed under Firefox 3.5 may be incompatible and/or require updates to work with Firefox 3.6. Please report any issues to the maintainer of the extension. When you install Firefox 3.6 all of your Extensions and Themes will be disabled until Firefox 3.6 determines that either a) they are compatible with the Firefox 3.6 release or b) there are newer versions available that are compatible.
This list covers some of the known problems with Firefox 3.6, which will be resolved in future releases:
- When exiting the browser, if you allow a web page to cancel the quit action then some features of the browser will no longer function properly. Normal function will return after the browser is restarted (see bug 537449)
- Some animated GIF files may not render properly, leaving small artifacts behind (see bug 538752)
- If you have the 'reading pane' option set in Hotmail, the scroll arrows will not work properly (see bug 511075)
- If FIPS mode is enabled and certain files have been removed from the system, the browser may crash on startup (see bug 522041)
- On some versions of OS X, Firefox will not be able to open local files from the Finder if they have spaces in the filename (see bug 530064)
- If the user repeatedly changes the paper size and asks for a Print Preview, Firefox may crash (see bug 495567)
- Firefox may have difficulty playing system sounds in some distributions of Linux (see bug 536996)
- Zooming out on some sites may result in grey or black lines appearing (see bug 468496)
- 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.
