(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 :)

Really good extension with all channel emotes but my favourite feature is the audio compressor.

A must-have for regular Twitch users. The 1-star review bombs are from people who don't understand how the add-on approval system works and accuse the devs for something they have no control over. The devs are great and they are real saints for putting up with Mozilla's shenanigans.

FFZ is a great community created addon which enhances the Twitch experience in more ways than I can count. When I view the site without my FFZ enabled, it's shocking to be reminded of what Twitch has become but the extension makes the site 10x better than without it. Emotes, QoL improvements, moderation features; FFZ has it all and does it better than 7TV or BTTV in my opinion. Thank you very much to the hardworking contributors on the dev team 💜

People rage rating this extension 1 star because Firefox takes their dear time approving new builds is just kid behaviour with no patience and inability to focus for more than 5 seconds on anything... Took Firefox a couple of days, probably not without encouragement from the FrankerFaceZ's devs, but still, they solved the problem with Firefox and the extension is working again. Stop being little babies throwing a tantrum the second something does not go your way...

Insanely good add-on. Twitch is trash without it.

People are so weird leaving 1 star when the dev can't do anything about it on their end.

Makes the Twitch experience bearable and always has an option to disable any tiny thing I find that annoys me about twitch ui. It even allows you to revert changes when twitch puts you in A/B testing such as when they put titles above the player. I miss it that it has been broke for so long. Hoping mozilla approves the new update soon!

EDIT: It seems like the update has now been approved! It says 13 days ago(probably when the new version was submitted and put officially in the review queue). But it is in fact working with the latest version of Firefox.
