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 (or at least "Gecko and not Chrome/CrOS/something else known to pretend to be Gecko"). And it's the "TV" platform that is triggering the resolution crippling.
The issue is that some of those techniques are only useful after the client has rendered the content rather than before.
But they are useful and completely valid ways of dealing with the problem.
It is not the end of the world if I have to click am extra once or twice to change the language. Hell most websites have much harder processes just to reject cookies.
Personally I would rather err on the side of slightly extra work the odd time I’m not on a website not in my native language than have an extra bit of information that can be used to track me.
Again take a look at the Gemini protocol, its a perfectly fine browsing experience without all the cruft.
Valid, but not standard and more inconvenient.
Additionally, you act like query strings can’t be used to track you when they certainly can.
Most of the advantages of Gemini are implemented in the client and not the protocol itself.
