I have checked my firewall settings and set firefox to be allowed and also checked my proxy settings and choose no proxy as your help section advises.

Worked fine yesterday. Now it won't work today. As I mentioned google chrome and internet explorer work fine.

Please help as I prefer to use firefox.

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again:

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version)

  • Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see Configure firewalls so that Firefox can access the Internet.
