I don't see any mention of the YouTube adblock trick, so from the vid:
Copy YouTube URL. Paste it in Bing and search. Scroll passed Bing's sponsored bullshit and click on the thumbnail for the video you searched. It will then play, still in Bing, with no ads.
So if you're on a work or government or w/e computer that doesn't allow installing adblock extensions, there ya go. No downloads or anything, just YouTube and Bing.
...this is the first time I've ever had any interest in using Bing, lol.
YT has been combating them, so they have some trouble lately. Others might be having trouble with the increasing amount of people leaving the Google regime.
Yewtu.be seems to be always strong (although you can't import your subs there sadly)
It isn't. But there are situations where that isn't an option, like being on a work or government computer where downloading firefox or installing an extension will get you fired. When that's the case, YouTube+Bing is a "good enough"/"better than nothing" option.
