After downloading Firefox I cannot get it to connect to the internet. I always get the message "server not found." I have tried all the "fixes" suggested online but without any luck. This is a new download and I have not used Firefox before now.

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.
