I had switched to Chrome a few years back, and had more recently switched to Opera (Blink) before it was bought up by the Chinese. I switched to Firefox when Nightly 57 was released, and haven't looked back since. Couldn't be happier. It's a pity so many long-time users of Firefox feel distraught about the Extensions kerfuffle, but fwiw if that allowed Firefox to get fast, then I was all for it. For my use cases, the available Web Extensions are enough. And I have even started to use Tree Style Tabs, while I was more than fine with regular horizontal tabs before.
