Hi Shane It is possible that your firewall or other security software 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 and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process. See: *https://support.mozilla.org/kb/Server+not+found *https://support.mozilla.org/kb/Firewalls *https://support.mozilla.org/kb/fix-problems-connecting-websites-after-updating ----- Try to start Firefox in <u>[[Safe Mode|Safe Mode]]</u> by holding down the Shift (Mac: Options) key to see if that helps. *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

Hi, can I get a tutorial on how to remove rules from firewall because some other apps don't have internet access too and I think that the firewall causes it

What firewall do you use? Some are listed here: *https://support.mozilla.org/en-US/kb/configure-firewalls-so-firefox-can-access-internet#firefox:win7:fx41
