Must join the choir and say that eventhough I have been a die hard FF fan, its gotten to the point of an impending divorce if performance doesn’t get better. I find myself switching to chromium more and more often. And then there are the extensions, that I sometimes can’t find for Firefox. That’s a minor annoyance than anything else though.
There are also a bunch of things that keeps me with FF. multi container tabs is one of my most loved ones. But I simply don’t get why the Team does make that feature even better. Like making it much easier to distinguish which container tab I am in. And adding even more customisability pr container-type.
Regarding DevTools, I really do t think I have a strong preference at all. But the stronger/more consistent performance the DevTools in chromium comes out slightly ahead.
For me it’s the overall experience which makes it a close race
