Hello everyone,

yesterday, out of the blue, Firefox is giving me this error page when I try to access to Google search, Amazon or Ebay . Other websites are still working properly. I always get this error and it doesn't let me move forward. I looked around to see any fixing at this problem, but nothing seems to help my case. I tried to reinstall it, clearing story, clearing cache, deleting the antivirus, firewalls, going into setting..really I tried everything. Nothing work. Any help? Thank you

You can check the connection settings.

  • Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
