Yeah, that's where nightly was when I still had it, with only a few, if important, extensions available.

But RES and old.reddit were no-go and made me sad. At least I had RIF (RIP IN PEACE).

Either way, glad to see it's getting wider support for all. I wish it worked that way in fruitymobileland, but at least there is a browser (Orion) that actually supports both FF and Chrome extensions that tries to make up for things.
