>IMHO Firefox didn't make me feel slow anytime

Agreed, used it since version 2. Been happy with it for over a decade.

It's not been flawless, but I never felt the need to jump ship. Flash used to be pretty slow on Linux and fullscreen video was sometimes a bit unpredictable. Of course, who cares about that now? :P The WebExtension transition was a bit premature in my opinion, but I think we're slowly getting there with new APIs. Prior to that, Firefox had the most rich functionality available to extensions of all browsers - and on mobile it's still better than Chrome.

Recently, it's been getting better. We had Developer Edition (though dev tools were always done pretty well in Firefox - I've been able to take screenshots of DOM elements via GLCI for 7 years, Google only got around to copying this feature in 2017), then Quantum. I'm optimistic about the future of the browser.
