everytime i try to open firefox i get a message that says "Firefox has stopped working. A problem caused the program to stop working correctly. Please close the program."
Sorry to hear about the crashes. It sounds as though Firefox is not starting up enough to even get the Mozilla Crash Reporter window. If you have seen that, your Firefox may have logged some data that would help track down the cause of the problem. You can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "Firefox crashes - asking for support" for steps to get those crash report IDs from the about:crashes page (or from disk), and then post some of the recent ones here.
Also and/or meanwhile, could you try starting up in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.
If Firefox is not running: Hold down the Shift key when starting Firefox.
If Firefox is running: You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" button > Restart with Add-ons Disabled
- Help menu > Restart with Add-ons Disabled
and OK the restart.
Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
Any less crashy?
