Was using my browser firefox, watching a yt vid and clicked to watch another vid and it stopped having network access. Confirmed firewall isn't blocking anything (even disabled it) and no proxy being used. Reinstalled 96.0 (was on like 95.X) no change --- update option in settings has no network access so I just downloaded it on another browser & installed (left the temp files alone) same issue. This is a software issue with Firefox, not a computer issue. Nothing was updated or change on the computer either and it just stopped working while on youtube. Restarted PC, no change. Disabled a few exts like adblocker & no change. PC is running macos 11.6, 96.0 firefox. Thank you for any help.
