I keep getting an error message saying "Unable to connect. Firefox can't estblish a connection to the server". This happens with every webpage I go to but if I try to use Internet Explorer these pages load fine. How do I fix this?

Did you check your security software (firewall)?

A possible cause is security software (firewall) that 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 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.
