Until FireFox releases a fix, renaming your Firefox exe file will fix this. Go to your Firefox folder (default C:\Program Files\Mozilla Firefox) and rename the firefox.exe to anythinghere.exe.
If you have desktop\start menu shortcuts, you will need to fix them by right clicking choosing Properties and fixing the 'Target" box.
That fix it up for you? It is a problem with the new update, only some people experiance it. All of them I have talked to have told me renaming the exe fixes the problem.
