When I open a combo box, sometimes I see some weird characters instead of content. Sometimes all pages are disappearing and I must minimize the Firefox and full screen it again to see the page.

Even in bookmarks it’s like this. This bug is after I installed firefox 4 I think. With 3 it was ok.

You posted with a Firefox 3.5.x user agent.
If you use Firefox 4 then Save mode also disables hardware acceleration.


In Firefox 4 Safe mode disables extensions and disables hardware acceleration. Try to disable hardware acceleration.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works in Firefox 4 then check if there is an update available for your graphics display driver.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

I tryed a little in safe mode and the issue has gone. In normal mode the issue is still present. I have only 3 enabled extensions: java quick starter, java console, and battlefiels ... I disabled them but it's still buged. Can I reinstall those extensions? How?
