Why can't I access any website for two days? Ken

Posted

For 2 days I have been getting the message "Firefox can't establish a conection to the server at ..." This happens with any web site and it's frustrating.

Internet Explorer works on this computer but I don't like it at all.

Chosen solution

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 and the updater process.
