One of the best extensions I use. Twitch is unusable without this extension.

The must-have extension for Twitch users. FFZ gives us many more options than other Twitch extensions and, dispite Mozilla's delays in making updates available, it's worth the wait.

firefox needs to get off their lazy butts and approve the latest version of this extension, the current one is out of date and doesn't work and even though it's fixed up stream. FIREFOX needs to make the next move and approve the update!

A must have addon for using twitch. Without, twitch is unbearable to look at. Only issue is firefox's slow approval of addon changes, gimping fixes to the addon when its inevitably broken by twitch.

Excellent extension, by far the best on Twitch. I'm currently running it thanks to Tampermonkey and the user script from its website, but during the days I couldn’t use it, I really missed it.

(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.

all these 1 star reviews lately are a real shame, because they're down to issues outside the developer's control. Twitch changed something with their website which broke this extension, and they've already written a fix the same day! but it's down to Mozilla's slow publishing system that we don't have the update in our hands already already, so give them a break. this is still the one and only best enhancement suite for Twitch

It was indeed a Twitch update that broke FFZ and the extension already got updated so just use the userscript version.

FFZ has honestly been a such a fantastic tool to use for all these years but once again I'm here to check what's going on with the addon as even the userscript version stopped working so you can't even blame it on Mozilla anymore. Frankly maybe some Twitch update broke FFZ. A lot of people reporting in Github too.

compressor button issue seems fixed :)
