I use a lot of Google products, but avoid Chrome because of nonsense like this. Firefox works fine for everything else EXCEPT certain Google products. Feels intentional
This is exactly why companies spend money on marketing, people remember these ideas and internalize them as their justification long after it stops being true. And Chrome being fast hasn't been true for a long time.
I can confirm this, Chrome wins the benchmark tests and some CSS rendering but lags behind in DX. I'm not sure where OP got the idea that Firefox has fewer features from a developer POV.
Chromium browsers have only 1 feature I need: access to the Chromecast API. I have 3, Firefox can't connect to them and the last 2-3 times I tried the listed 3rd party methods (fx bridge, etc), I could never get it to work.
I had a similar need, and it prevented me from moving to FireFox for a long while. Luckily, I did manage to get fx_cast to work, and it's been flawless ever since. In fact, I'd say it work more reliably than Chrome's casting!
That's a bummer. Personally, I use an app made to cast web video on android because it has better casting experience (including subtitles support) and wider range of supported websites. The dev is also responsive and would push a fix if you report any site where it doesn't work: Web Video Caster
On Android tablets, most non-Firefox browsers support a tab bar, and tablet optimised UI. Firefox is just a giant stretched phone layout. I like to use the same browser on all platforms so I can sync tabs, so Firefox being crap on my tablet rules it out for my other devices too.
