(09/05/2025: FFZ isn't working currently on Firefox due to TWITCH changes. FFZ was updated within 4 hours of the change, which you can access on the userscripts version. Install using Tampermonkey from the FrankerFacez website. Unfortunately MOZILLA still hasn't verified the update, resulting in the longer downtime for the Firefox version.)

Works great, consistently better than BTTV and 7TV while supporting both.

Great developer, great piece of software, lots of options that are absolutely not offered by any other competing products. Competitors are busy charging money and attending events and sponsoring streamers while mired in a bunch of controversies and even got their start by embracing racist banned emotes.
