At some point there were more than 1 relevant browsers using Gecko, though. Somebody at Mozilla decided to gloriously triumph over allies by killing XULRunner and not offering a replacement.

Not sure if WebKit is such a bad choice in that context.

It really is telling that even Microsoft don't find it viable to maintain a browser engine.

The "standards" are an absolute fucking nonsense, and boil down to "just do what Chrome does because nobody can stop them".

have any instance admins ever shared the browser stats?

Not strictly true. Firefox gets inferior support from cloud services, like Microsoft. Newer versions of their Web apps are not available on Firefox.

But there should be no downside. It's all artificial.

One thing I miss in Firefox is tab grouping. Yes there are 3rd party extensions that do that. But Chromium based browsers support that natively.

Dunno if this helps you at all, but I've been using BitWarden to manage my passwords since I made the switch from Chrome to Firefox (both on PC and my Android phone). It doesn't fill passwords automatically in either case, but it's not much extra work to invoke BitWarden to fill those fields as-needed on either device, and it works very consistently. It's also (I'm told) much more secure. Just thought I'd share that here!

It runs great now. Most importantly, it supports extensions like ublock.

Firefox on Android is fine, except they insist upon disabling about:config on the main branch of the browser for some damn stupid reason. You have to use a nightly or beta build to be trusted with your own config that much.

Personally, I ended up switching to the Fennec fork over this.

Yeah, it's alright.

You can install an ad blocker in it, so it's automatically better than Chrome.

With that and a few cookie popup removers, it's almost like the web is usable again.

Given Google and YouTube's history of intentionally and maliciously disrupting other browsers that aren't chrome, it'll be a safe bet that it's intentional.
