I only see the thumbnail of your screenshot, the full image seems to be lost.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

You can delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required.

See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions

If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.


Your plugins list shows that you have the Mozilla ActiveX plugin installed.

  • Mozilla ActiveX control and plugin module


The Mozilla ActiveX plugin is not compatible with Firefox 2 and 3 and you should remove it. For instructions on how to remove the Mozilla ActiveX plugin see: http://kb.mozillazine.org/ActiveX
