I did not switch to Chrome a few years back because it was better, but for because Firefox was worse. If both would've worked fine I of course would've not changed.

I don't know about today, but a few years back starting up Firefox was painfully slow, and when an update arrived it would first nag you about it and then during restart started checking for extension compatibilies. Even using felt sluggish and was temporarily fixed by running the sqlite vacuum in it db.

Chrome for whatever reason had none these issues, and it felt even slightly nicer to use, with usability enhancements all around like more fluid animations in tab moving, and all settings on a nicely laid out web view instead of a tiny modeless window with 10 tabs.

I really hope Firefox can not just catch up, but go past Chrome. Unfortunately the last time I tried it not too long ago, it didn't start but instead wanted to show that it is checking for extension compatibilies. Didn't exactly fill me with excitement.
