Attached: 2 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.

    From what I can understand from the thread, they aren’t deliberatly crippling FF.

        The way I read it is Chrome gets a pass on the architecture crippling, the others don’t.

        Someone correct me if I got the wrong idea.

          So Google is saying out loud they are trying to be Microsoft and abuse its near monopoy to push their other products.

          Got it.

        It looks like also this was against adblocker so, again, not specifically Firefox. Quote from the article itself:

        The issue was initially reported as targeting Firefox users, but users online have said they’re seeing the delay in Chrome and Edge, too. Reddit and Hacker News users who’ve examined the code that appears to be causing the delay have said they see no indication that YouTube checks what kind of browser is in use. Mozilla’s senior brand manager Damiano DeMonte wrote in an email to The Verge that “there’s no evidence that this is a Firefox-specific issue.
