One problem I have with Firefox on Android is that it doesn't support the Samsung DeX desktop environment, while all the other browsers do (Chrome, Edge, Bing, Samsung Internet). Presumably that means it doesn't run well on ChromeOS laptops either. It's also noticeably slower than the other browsers. That said, I keep going back to Firefox as my preferred phone browser, I still like it more than the others. And Firefox is definitely my favorite desktop browser, ever since Quantum. It was an enormous speed improvement over Safari on Mac for me when it came out, and I'm enjoying Firefox on my new PC laptop too.
