Not anywhere near as extensive as FrankerFaceZ, but it has some useful functions that FFZ lacks, in particular ability to join chat anonymously. I use both BTTV and FFZ for different reasons and they don't conflict with each other, both great extensions on their own.

completely awful. Doesn't work 90% of the time and Twitch is useless without it.

Currently its bugged and is making the video small when you have the chat set on the left side of the window. Otherwise it's a good app.

Pretty good but settings get reset to default on browser restart... Also, there's no way to disable specific emotes?

Addon has never worked in Firefox since I moved over at the start of the year.
