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.
Easy: use a user agent switcher that uses blacklists. Mine only spoofs chrome for youtube.com.
Thanks, will definitely check out this unnamed extension.
Here’s one, though several others offer the same functionality.
Custom mode:
Yeah I used a user agent switcher that didn’t seem to have a blacklist feature that I could find and it broke every cloudfare site.
