Attached: 3 images Today I learned that YouTube is deliberately crippling Firefox on Asahi Linux. It will give you lowered video resolutions. If you just replace "aarch64" with "x86_64" in the UA, suddenly you get 4K and everything. They literally have a test for "is ARM", and if so, they consider your system has garbage performance and cripple the available formats/codecs. I checked the code. Logic: Quality 1080 by default. If your machine has 2 or fewer cores, quality 480. If anything ARM, quality 240. Yes, Google thinks all ARM machines are 5 times worse than Intel machines, even if you have 20 cores or something. Why does this not affect Chromium? **Because chromium on aarch64 pretends to be x86_64** `Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36` 🤦‍♂️​🤦‍♂️​🤦‍♂️​🤦‍♂️​🤦‍♂️​ Welp, guess I'm shipping a user agent override for Firefox on Fedora to pretend to be x86. **EDIT**: The plot thickens. Pretending to be ChromeOS aarch64 *still gets 4K*. Specifically: `Mozilla/5.0 (X11; CrOS aarch64 10452.96.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36` still works. **EDIT 2**: OK, so the plot *really* thickens now. Chrome is not affected even if it claims to be aarch64. Turns out there is another codepath: apparently YouTube thinks aarch64 Firefox is... a HiSense TV?!?!?!?! Specifically, model 65a67gevs...????? This is *server-side* sniffing now and it's *specifically* looking for Firefox aarch64. And it's the "TV" platform that is triggering the resolution crippling.

      It’s the same with all the other frontends (LibReddit, Nitter, etc.). They never work and everyone is just like “try a different instance!”. How many dozen different instances should I try before I give up?

      Shout out to Stealth (Reddit) and Squawker (Twitter), those both work the vast majority of the time without any “instances” to depend on or switch through.

        Google is blocking popular instances these days, so yeah, you basically need to find an unpopular instance, which usually means it’s new and may not live for long, or it will quickly become popular, because it works, which will cause Google to block it.

        there’s a browser extension called libredirect that has a keyboard shortcut to switch between instances. you can also use freetube/newpipe/mpv.

        I tried it and my main complaint was it was like 720p, so lower quality (noticeable to me just looking at it). But it “just worked” for me. But I’m also not interested in YouTube enough to play this game - if they block me, I stop going there. It seems like they give up blocking me every so often (or something updates IDK).
