While using Firefox my web pages suddenly stopped loading. Checked my wifi, it's all good. I rebooted my computer, still they won't load. Ran a malware scan, pc is clean. Checked other apps that use internet, they all work. Tried to open Firefox in troubleshoot mode since I figure it's probably an add on. When I hit the restart button, instead of confirming I want to use troubleshoot mode, nothing happens. Go to uninstall it, they ask if I want to refresh instead so I say yes. Browser refresh works for about 30 seconds and then stops loading the pages again. This time I completely uninstall and reinstall it, same thing, works a few seconds and then breaks again. If anyone has more solutions I can try, I'd be very grateful. Thanks in advance.
