Yea i only just replaced my ip address with x's there on the screen just to not expose it ya know ? but i swear i didnt touch anything else.
So then i should try something else in that "general.useragent.override.youtube.com" thing ?? I just used what grey_rat said earlier -- Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A403 Safari/8536.25
Well okay... i changed the 5.0 to 4.0, and the 6_0 and 6.0 to 5.0 -- didnt help
I then then tried pasting it in firefox's "responsive design" user agent box -- and then the yellow label showed up at the top "we'll stop supporting this soon" and a blue label "you were redirected to desktop, return to mobile [button] ...didnt help ...so i clicked the return to mobile, and then viewtube instantly showed an error about "cant load video player" ..like it didnt work with it whatsoever period.
I googled a couple "online youtube ripper" websites cause i was curious. and they all have the googlevideo url when saving from them..
is there some way to force youtube to load from that googlevideo.com instead of youtube.com ??
edit 1: I noticed something in the "playback/performance" page of youtube settings. First of all, its totally worthless showing only "captions/info card" but if i clicked "no style" under View --> Page style -- and scroll all the way down the page, i saw a bunch of AV1 related descriptions.
Is that only for chrome or something ? How can i get those to show up in firefox ? Or wont matter ?
edit 2: oh my god, after all this time for countless hours of trying a billion things, i just learned what's finally going on! if i signed out of youtube, the video finally loads! and from the googlevideo.com link instead of youtube.... but if i sign back into my account (kuja killer) ..then it wont load at all ...back to the youtube.com link again. Apparently my youtube account is f***ed up. I tried clearing cookies and cache, which made me have to log back in again, and that didn't work.
But there's no freaking playback/performance settings except "captions/cards" seriously this just makes me more mad. I know there was always settings for this before like "never play high quality videos, always low quality" or like about having slow internet. I know for a fact that i kept it on the low quality/slow internet option before.
so it wasnt windows media player (not yet ?), it wasn't k-lite basic pack ...not codecs...not registry edits/firewall ...nothing. Apparently my own youtube account is what's screwed up with no such options anymore to fix...
