Firefox suddenly disappears, but still running

Firefox suddenly disappears from the screen and the icon too, while it is still running. When I try to reopen it, a window pops up to warn that Firefox is still running. I have to close the session from Task Manager (End Process firefox.exe from Processes tab). This happens only on my account. I do not experience this problem on a different account.

I have XP sp3.

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 or otherwise make changes.

Disabling hardware acceleration resolved the problem. Thanks.
