Interesting. Firefox android works great for me, but Firefox windows gets very slow on my machine. I don't use their password manager on either, though, so I can't attest to that.

This is why I don't use FF (although I'm on Linux). It's unusably slow for me. My experience is not the most common one (indicating that there's something about my ecosystem that FF hates), but I haven't been able to make FF work in any of the releases starting a couple of years back, I think.

I don't browse on my phone at all, so I won't be using FF there purely for that reason.

Is it still slow for you? Have you tested it recently?

Yes, it's still my default browser -- work and home. I put up with it because I browse far more on my phone than on my computer.

Firefox Android OOMs whenever it sees an article from The Guardian.

This is just more anecdata, but I'm exclusively using Firefox on Android and have never had issues with The Guardian. In fact, at this very moment there is a Guardian article linked on the front page, and I've visited it without an issue.

I don't doubt your experience, but it's clearly not universal.
