I have an issue with Firefox which makes me unable to use it. All tabs flicker. It looks like they are refreshing very rapidly. When I try to open a page in a tab, I got nothing (looks like back button is fireing and then refresh, refresh etc...). How can I solve this?

It sounds like you have acceleration enabled, a feature known to cause problems with some graphics configurations.

Open a new tab and type about:config. In that tab search for layers.acceleration and switch:

  • layers.acceleration.force-enable to false.

If it's already false, try switching:

  • layers.acceleration.disabled to true.

Restart your browser.

If you cannot access the about:config page, add these lines to the prefs.js file of your firefox profile:

user_pref("layers.acceleration.force-enable", false); user_pref("layers.acceleration.disabled", true);

It didn't help :( – Paweu Oct 25 '12 at 18:49
Sorry to hear that. Have you tried running it with no add-ons, a clean profile or newer graphics drivers? – zmode Oct 25 '12 at 18:51
Not yet. But what could caused this? Tommorow morning everything were running perfectly. I just furned on my PC and I got this error. – Paweu Oct 25 '12 at 18:59
@Paweu Could range from a firefox update or an OS update to a hardware problem. Let me know how trying the above goes. – zmode Oct 25 '12 at 19:01
You'll have to disable them one by one to figure out which one causes the issue. – zmode Oct 25 '12 at 20:07

This is not a complete fix but if you minimize the browser window and lower it by 3 centimeters from the top edge revealing your desktop background, it should stop the tabs from flickering.
