There may be a problem with the profile (location where Firefox stores user data). The profile is not normally removed when Firefox is uninstalled.

Try running the profile manager and create a new profile, for details on doing that see Creating a new Firefox profile on Windows - MozillaZine Knowledge Base

I tried entering firefox -P at in the appropriate dialogue box in windows 7 and nothing happened except firefox started as a service. I even went to %appdata%\Mozilla\firefox\profiles and deleted everything there (I deleted everything in in %appdata%\Mozilla when uninstalled firefox and reinstalled it again.

I even thought it might be something wrong with the install file so I downloaded firefox 3.6.11 but that didn't work either.

I am really puzzled.

Anyone?

I'm still unable to run firefox on my Acer AspireOne running win7. It did work up until 2 mos ago but then stopped and even if I do a complete uninstall and reinstall I get the same problem.

Please can anyone help?

Thanks,

Dov

I followed these and got things working again :-).

Please IGNORE this response, it is for Linpus Lite Linux, NOT Windows 7
