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

• Don't make any changes on the Safe mode start window.

See:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
• Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

• Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
• Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

There are other things that need attention.

Browser is now working. It was a toolbar that I had that was the problem. I suppose windows 7 doesn't like yahoo toolbar even if I did. Anyway I am not sure if I downloaded the correct java that you told me to download. The one I download and installed was jre-6u22-windows-i586.exe. Can you verify if this is the correct one? Thanks for all your help with solving my problem.
