Start Firefox in Use Troubleshoot Mode in Firefox 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
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit") --- Your plugins list shows that you have the Mozilla ActiveX plugin installed. 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
Your plugins list shows outdated plugin(s) with known security and stability risks.
