I can't access anything with my new version of firefox

I’d first check whether Firefox is actually connecting or just hanging. Try opening''' Help → Troubleshoot Mode '''and load a few sites. If nothing works there either, check Settings → Network Settings and make sure it isn’t set to a manual proxy. Also try entering '''https://example.com''' directly in the address bar. If that just sits there with no error, tell us what happens in Troubleshoot Mode and whether Edge can still access the internet. That will narrow it down quickly.
