Known Issues
This list covers some of the known problems with Firefox 3.5 which will be fixed in future updates or releases:
- After installing this version, users will not be able to return to a previous beta version of Firefox 3.5 without creating a new profile (see bug 488966)
- Restoring your bookmarks from a backup can take some time, during which the browser may seem unresponsive (see bug 493731)
- If a pop-up window is focused when you enter Private Browsing Mode, the Location Bar in the first Private Browsing Mode window will not be editable. Opening a new window fixes the problem (see bug 495495)
- After using Clear Recent History some SSL sites will not load all images and styles without pressing reload (see bug 480619)
- Firefox 3.5 will only support color profiles as specified by ICC v2, later versions will add support for ICC v4 (see bug 463221)
- Users viewing images using ICC v2 color profiles on monitors with wide gamut levels may find them to look more saturated (darker) than expected (see bug 497363)
- Websites using the new downloadable font support that wish to change the color using :hover will also need to add text-rendering : optimizeLegibility for font sizes less than 20 pixels (see bug 495455)
- Some sites with Flash can cause problems with the Cookies dialog (see bug 495035)
- Web pages can no longer automatically install PKCS11 cryptographic tokens. Users are now required to do this manually or install an Add-on that installs them (see instructions and documentation)
- Pressing enter in the Location Bar will not do anything if you are running AVG SafeSearch v8.0 or lower. Upgrading AVG SafeSearch fixes the problem (see bug 479095)
- If you select Fax from the Print Dialog, the Windows Fax dialog will appear and then disappear. Faxing still works from other applications (see bug 440486)
- If the user repeatedly changes the paper size and asks for a Print Preview, Firefox may crash (see bug 495567)
- Zooming out on some sites may result in grey or black lines appearing (see bug 477552)
Troubleshooting
- 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-mode
and 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.cd /Applications/Firefox.app/Contents/MacOS/
./firefox-bin -safe-mode - 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.
