I'm on my cousin's computer, and she's using Internet Explorer because when she downloads FireFox, it opens and says there was a problem connecting to the internet. Does anyone know why it does this and how to fix it? We've tried the obvious (uninstalling and reinstalling and restarting the computer).
Sounds like her firewall is blocking it. Reconfigure it.
Windows Firewall > Exceptions > tick Firefox. Or look up the port Firefox uses.
I reconfigured the firewall and it didn't work.
Turn off the firewall completely and run FF. See if it still acts up.
Check out internet options of your pc i think there is a problem.
