1. Mozilla’s goals for the web line up quite nicely with my own.
2. The performance is good for what I want.
3. The extension API is more powerful than Chrome’s.
4. Outside of the Apple ecosystem, it’s the last major alternative to the Chrome skins.
5. It isn’t actively trying to cripple adblockers.

Is not chromium, has a good UI, supports manifest v2, is open source and have native support for autoscrolling on linux

It’s not Chrome or Chromium derived. Google has incentives to mine me for data. Mozilla, not so much. I don’t trust Mozilla completely, but I certainly trust them more than Google to have my best interest at heart.

There are other reasons, but if I had to point only one word: containers.

Switched to Chrome a few years back when Firefox killed XUL and bundled too much bloatware.

Now I’ve switched back to Firefox because it’s good again and Google is doing too many evil things lately (Web Integrity).

The mobile version has addons like ublock-origin and bottom search bar. Plus, Chrome wants you to enjoy the web, which is full of ads. I don’t, that’s why.

Supports extensions on mobile

Because it has tabs. Seriously, I first used Firefox back when IE6 was the norm, and Firefox brought tabs and better standard compliance. Haven’t turned my back since.

1. It’s faster
2. It’s not chromium-based
3. It can protect you from trackers and block ads
4. Chrome may terminates Adblock-functionality extensions in Manifest V3 and Firefox wouldn’t, afaik

Container tabs. No more need for separate chrome profiles.

Ad blocking on desktop and mobile is awesome.

And it’s vital to have multiple browser engines in the wild for interoperability. If we go all Chromium-based, we’re going to eventually pay for that like IE6.

And Google is kind of an untrustworthy POS of a company these days.

Because it is fucking awesome.

Plus on mobile, I likes my ublock, dark reader, etc.

Because I like having RAM to spare

I have been with Firefox, since it’s inception. Never left it. And it never let me down.

Because I hate ads.
