I opened Firefox. When I try to get into any website, the error message 'unable to connect" appears. I switched over to Internet Explorer and it work fine - I can connect to the Internet with no problems. So, what's going on? How can I fix it?

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
