Sorry to hear about the crashes. If you are getting the Mozilla Crash Reporter form, 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, and then post some of the recent ones here.

Meanwhile, let me mention something that is going around in case you have this problem, too:

Firefox is crashing within seconds of startup if you have either of the Applian Technologies programs Freecorder or Replay Media Catcher in combination with Norton security software (and possibly some other security software).

If you have either of those Applian programs and it isn't essential, try uninstalling it and then restarting Windows to ensure that none of its components are left running.

Will Firefox start normally after that?

(If you prefer not to uninstall the program, another user said he used msconfig to prevent FlvSrvc.exe from running at startup and that fixed it. See: https://support.mozilla.org/questions/1086722#answer-789197)

Try to start Firefox in Safe Mode by holding down the Shift/Options key to see if that works.

If you have submitted crash reports then please post the IDs of one or more recent crash reports that start with "bp-":

• bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

You can find the report ID of recent crash reports on the "Help > Troubleshooting Information" page (about:support).

• click the "All Crash Reports" button on this page to open the about:crashes page and see all crash reports.

Alternatively you can open about:crashes via the location/address bar.
