Oddly, I actually can't watch YouTube without using Mullvad, my ISP does some weird-ass something that causes even 480 forced videos to buffer every 3 seconds or worse. Sometimes they just won't load. With Mullvad on everything plays at 720/1080 seamlessly.
It's especially odd because every other everything on the internet is fine. It is only YouTube.
Maybe it's more a FreeTube thing? I detest Reddit but every once in a while it comes up in my search results with a potential answer and I get "blocked by network security" makes jerkoff motion. The obfuscation mode is set to auto but there's 3 options and I have no idea which is the best choice overall.
Oh I can never access reddit. I have Opera Browser installed and configured for privacy + its VPN active in case someone sends me a reddit link. It isn't perfect but it at least loads, if I deem it important enough to click.
