Are there any updates to this issue? Any known causes or work-arounds? It would be nice to know what firefox add-ons are installed on the machines that are running into this problem. Here is a list of my add-ons:
CodeBurner 1.1, Firebug 1.3.3, Firecookie 0.8, FireFTP 1.0.4, Inline code finder 0.93, java quick starter 1.0, MS .NET Framework assistant 1.0, Pixel perfect 0.6.1, Web developer 1.1.6
I tried to disable all of the add-ons to see if that solved the problem but no luck. I haven't gone as far as to uninstall my add-ons but I might try that next if people think it’s even possible that an add-on could be the cause of the bug.
