Firefox periodically crashes several times a day over the past few months. The last few days, Firefox began to crash almost every time when i try to open absolutely different web sites. All other software i use and other browsers don't crash at all.

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

I do not have any problems connecting to Internet. The problem i have is not a problem with firewall settings. It's a problem with FF crashing.

See if there are updates for your graphics drivers https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration

Make sure all programs are up to date.

more options

Version of graphics drivers installed is the latest version available. Besides, all other software (games, for example, that use graphics resources more than anything) work perfect.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
