[[Firefox can't load websites but other browsers can]] In case an add-on has updated in a way that interferes with Firefox connecting to sites, you also could test in Firefox's Troubleshoot Mode.

''If Firefox is running:'' You can restart Firefox in Troubleshoot Mode using either: * "3-bar" menu button > Help > Troubleshoot Mode... * (menu bar) Help menu > Troubleshoot Mode... and OK the restart. A small dialog should appear. Click the Open button. ''If Firefox is not running:'' Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button. ''Note: Don't use the Refresh without first reviewing this article to understand what will be deleted:'' [[Refresh Firefox - reset add-ons and settings]]. Any improvement? Ref.
