earlier, we could use extensions(except for 7-8 highly poplar ones) with an account containing add-ons collection(in nightly versions). But now it's coming to beta and stable as well.

Yeah, I used Firefox nightly until uBlock Origin became available on the regular release. Glad to see that most are going to be available. Been using Firefox since before they refactored the entire codebase (I think it was Mozilla Navigator back then). Went to Opera for awhile, Maxthon, and Chrome when it first game out but I always had Firefox installed.
