It was faster for about a year. And at what cost?
Then things got to the point where developers started doing the "IE thing" and only testing with Chrome. Developers were complicit in this because they repeated the same mistakes of the past. It's amazing how just a few years pass and the next wave of developers are oblivious to what came before.
My move to the latest (quantum?) Firefox has been beset by horrific energy use problems on macOS. Those have only just been fixed, but things are much better now. I hope the FF team keep their focus because with Microsoft and Opera giving up on their engines we need Mozilla more than ever.
Not all developers. In fact I remember quite a few meetings where I couldn’t convince product that Safari and Firefox should be supported and ended up leaving the meeting yelling “Fine I’ll support them myself”. To this day I still test in all 3 hoping one day I can stop testing in Chrome.
I switched back around then, because now it's fantastic.
