Just like IE was.
And just like in the IE days some of us are cheering enthusiastically for every better alternative while others are defend the incumbent alternative :-)
It will take time but if we all do something sooner or lesser the old "best viewed in IE6/Chrome" websites become an embarrassment to management and then it will get fixed ;-)
Edit: Same will probably (IMO) happen with WhatsApp now and possible (again IMO) even Facebook and Google if they don't catch the drift soon. I can sense a massive discontent with them everywhere and for at least a 3 different reasons: spying, ux and functionality regressions and also because of their stance on politics (ironically I think large groups on all sides of politics want to bludgeon those companies over various issues and few except investors really love them).

Safari and Firefox also are up since October, but I'm not sure why that is. For Safari I suspect new Apple devices being purchased around the holidays, but that's just a guess.
As a backend dev and security focused eng I have little reason to test drive changes in all browsers.
FF has been smooth and stable for me across desktop OSs. Having no reason to alternate between that and Chrome, I’ve been confused by people saying it’s slow.
It’s been, to my memory, a flawless experience for 3+ years.
On the flip side, Chrome is a spy app, and a cognitive perception of web devs it’s faster does little to move me to use it.
May be try on new profile to isolate the issue.
That being said I use 90% FF, 9% safari and 0.999...% Chrome, because FF handling of tabs/containers/add-ons offers superior UX despite the performance annoyances. IMO, obviously.
I've noticed reddit is rather slow in ff but other than that not really nocoed anything massively slow or broken.
