Everytime I request anything I get this: "Requested URL not found: 400"
I have Total PC health and it asked to update a URL driver. Since then I get the same error when ever I try to do something on firefox. I restore total pc health, but nothing is right. I've uninstalled firefox and reinstalled firefox, still nothing. Same error each time A error occurred: Requested URL not found: 400

If that is a firewall then try to remove all Firefox rules in that firewall including rules for the plugin-container and updater program.
I found my problem was linked to AVG's link scanner. If I disable "Enable surf-Shield it fixes the "Requested URL not found: 400" but a warning from AVG will follow.
