Firefox periodially "restarts" All open tabs are closed, but the program itself remains running. Version 31 Windows 7 Pro x64

Posted

Firefox periodically closes all open tabs. The program itself remains running. The only open tab remaining is a home page tab which happens to be blank in my case. No error messages, just a quick blink and all the tabs are closed.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

You can also check for issues caused by plugins and set all plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page (plugins are not affected by Firefox Safe Mode)
