YouTube is deliberately crippling Firefox on ARM systems - eviltoast

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.

    Edit 2: Well, at least I know I’m right. Downvote away.

    Sorry, I’m all for net neutrality, but behavior based on browser usage, while dickish, has nothing to do with it.

    Edit: it seems like I’m being schooled. Got any sources to back up your downvotes?

    Edit 3: nope. I’m not being schooled. The downvoters should either get better informed or stop downvoting with their emotions.

      Hmmm, not sure why people are downvoting…

      Maybe these days people are using the term “net neutrality” in a broader sense to just mean equitable access, rather than the specific meaning that’s been used in the past to refer to ISP behavior and giving preference based on how much is paid?
