The second I disabled that panel, Firefox stopped crashing.
I finally figured out the problem… I’ve got a Wacom Intuos3 tablet hooked up to my computer, which enables the Tablet PC Input Panel in Vista, which caused the problem even if it was docked in the background. I’d create a blank profile, run in safe mode… and Firefox would crash on me every 2 minutes. The infuriating thing was that I could copy the profile to another machine, and it would work fine. I’ve had crashing problems for the last few months, starting from beta 2 and continuing all the way through the release. Note that setting compatibility in Vista doesn’t seem to help as much in my testing… but your mileage may vary.ĭo NOT Use the Tablet PC Input Panel (or OnScreen Keyboard)
Set the compatibility back to Windows 2000, and it might solve the crashing issues for you. Just right-click on the shortcut and choose Properties, then the Compatibility tab. Some Windows XP users might experience crashing issues that can be solved by using Compatibility Mode. XP Users: Run Firefox in Compatibility Mode
This is a good idea to do every so often anyway, and it can’t hurt. You can just open up the Clear Private Data from the tools menu, and clear out all of the junk at once.
There’s a known problem with the download history becoming corrupted and causing crashes when trying to download files. If running in Safe mode keeps you from crashing, you should go through and disable all your extensions, and then enable them one at a time until you find the one causing the problem. In the same screen as above, you can also disable extensions. Note: For me, disabling Silverlight fixed a lot of the crashing issues. If Firefox works fine after disabling all the Plugins, then you can enable them one by one until you figure out which one caused the errors. Open up Tools \ Add-ons, and then go to the Plugins tab, and disable anything you don’t actually use.įor troubleshooting purposes, you could just disable all of them… this is especially helpful when Safe Mode fixes the issue. One of the quickest ways to crash Firefox (or any browser) is to run with a plugin that is causing problems. Note: This method usually solves any problems caused by upgrading an old profile to a new one. You can export your bookmarks from the current profile and then import them into the new profile (covered below).
Open up a command prompt, or simply type in the full path to firefox.exe, and add on the -profilemanager switch at the end to launch the Firefox “Choose User Profile” screen, where you can create a new profile or switch to a different one.Ĭreating a new profile will give you a “blank slate”, where you might have less issues. You should also check the “Other Known Issues” section below.Ĭreate a New Profile (if Safe Mode Fixes Your Issue)
Select your new username in the top pane and in the lower pane (Permissions for ) check the Allow box next to Read.If safe mode does not solve your issue, then you should try to use compatibility mode (mentioned below), and do the uninstall completely and reinstall method.

I had the same problem except mine was IE7.
I know this isn't a tech support forum but I would suggest trying this to see if the problem lies with Silverlight itself and not Firefox.
