Unable to login with Firefox

[Floyd]

Good evening

For several days now I can not connect to the net with firefox. (It works with IE) it says "address not found".

So I analyzed the pc with spybot, a-squared, malwarebytes' anti malware, ad aware. Results: nothing to report. So I uninstalled firefox, redownload and reinstall but still no way to connect with firefox.

Have you any idea how can i fix this?

I had the same problem. I have Zone Alarms installed. When i opened Zone Alarm it gave me a pop up stating "Mozilla Firefox is trying to access the internet, do you allow it" - I clicked yes and walla! It worked.

Reset your Internet security software's permissions for Firefox (this includes antivirus and antispyware programs, firewalls, and more).
