I only switched from firefox to chrome, many years ago, for two reasons:
1. Better dev tools 2. Better WebGL performance
But today, Firefox has upped their game on both, and really, I don't play much with WebGL anymore so it doesn't matter that much to me.
I am kinda sick of this whole back-and-forth thing, though. I'm also getting tired of seeing the way the web is going; monetized and walled off. More and more, I'm starting to look into and toward distributed solutions.
Give me back the internet I remember from the early 90s. If I can't have that, then I might just return to BBS-ing over ssh...
