Firefox is my favorite browser. Not because I like it more than other browsers. But I think it is very important that there is not just a single browser engine on the market. Chromium has too much market share. And although it is open source google dictated what features get in. We shouldn’t trust one company with that much power.

I've been using FF more lately because it has a functioning ad block. Mobile web has become borderline unusable with the amount of ads that get shoved in your face. It's not enough to take up 90% of the screen, it has to pop up autoplay videos with audio over that last 10%.

Preach. Using my iPhone, I clicked on an HN link to Tom’s Hardware earlier today. Readable text occupied less than 1/4 of the screen. Everything else was taken by various banners, modals, etc. I tried to scroll down a little. It jumped back to the top of the page every time I tried, then started reloading itself. So, in sum, I read one(ish?) paragraph of a post before giving up.

I don't have problems scrolling in Firefox mobile that I've noticed, and I don't run flagship phones (I'm running a few years old Galaxy A51). I do run uBlock on Firefox Mobile though, which I'm sure helps immensely, so maybe that's the main difference.

I have no problems with FF mobile on iPhone.

Any browser on iOS is forced to use the Safari rendering engine. Firefox on Android is very different to iOS

Yeah but I don't have any problem with Firefox on Android. I'm typing this on a Samsung A40.

That's an Apple problem. The solution is simple: don't use Apple.

I have a late model samsung and browsing a news site like NYTimes works better with Vivaldi than with FF. FF seems to stutter if I scroll quickly, as if getting "snagged". Maybe Vivaldi is preloading resource vs. FF trying to load stuff realtime while scrolling? I'm taking a wild guess.

It was annoying enough for me to make the switch.

Firefox has sync, but it's opt-in, not opt out. You have to login.

Vivaldi is non-free closed source software.
