Firefox works fine but will not load RT.com on my PC.? (Note: Firefox works fine on my laptop.)
Server not found
Firefox can’t find the server at www.rt.com.
Check the address for typing errors such as ww.example.com instead of www.example.com If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Update your FF. A possible cause is security software (firewall) of computer or antivirus 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.
