doesn't work

(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.

Broken, doesn't work

currently broken

I 100% agree that this is the best extension for Twitch hands down "when it works". I wish Twitch had the compressor natively for example. However, I find myself using the Userscript/Tampermonkey combo somewhat regularly. The FFZ Dev/team is quick to at least start looking into issues and getting fixes out as quickly as they can though, can't ask much more than that. Like others have pointed out, almost always, Firefox is the one being the slow party.

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

The best twitch extension when it works. But it has been broken pretty often in recent months.

When it works, it's a fantastic add-on to Twitch that provides access to a ton of emotes, customization settings, and tweaks you can use to make your viewing experience better!

With that said, "when it works" is the big caveat. Ever since Mozilla required it to be listed on its Extension store, the app has been going in and out of functionality. Any time Twitch seems to act up, you can directly tie it to FFZ. It could be Twitch updates, Firefox updates, and things outside of the dev's control, but every time it has issues, it really ruins your viewing experience.

Before, it forced the viewing size of the stream to fit onto a 1920x1080 monitor, even though mine is much larger. I couldn't change it without going to fullscreen, which doesn't let you chat. Now, it's resizing the stream to only work with Theater Mode. If you are not viewing the stream in Theater Mode, the volume and play/pause buttons are not visible, a chunk of the stream is not viewable, and all of FFZ's functionality is gone. It took them a couple weeks to fix the first issue, and it may take a similar amount of time for them to fix the current issue. In the meantime, you have to decide whether you want to uninstall FFZ and wait until it's fixed and restore your old settings, or wait until it's fixed and deal with the borked experience in the meantime.

I know the devs are working as hard as they can and you cannot put the blame on them for Twitch/Mozilla doing what they want. I'd still recommend it for the best Twitch viewing experience, but just know it comes with a cost.

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.

Nice add-on if it didn't keep breaking or if settings didn't constantly work.

Just like BetterTV, it's broken and disables the ability to chat.

Would be 5* but it would be nice to be able to control emote size manually :D. Also i doubt it but is there a way to be able to resize chat like a windows window?

For a bit more than a week constantly emotes not loading! Recently very frustrating to use this addon! Shame!

It's not developer's fault but this extension keeps breaking and Mozilla's policy of updating add-ons is painfully slow, with all that in mind I suggest using Violentmonkey script. It's the exact same thing, using the same settings (you won't lose settings), that is updated much faster. This is a 5 star addon with 1 star issues caused by external factors.

Good addon but I need to use the Script since the Addon doesnt work for me. Please update it

Usually a great extension, but is just very very buggy lately. You have to re-enable the compressor manually regularly (within the same session sometimes), most modules are broken. This causes some visual bugs.

May be fixed soon I guess !

compressor button issue seems fixed :)

it is completely useless, like every single Twitch add on, coded by inexperienced people and broken 90% of the time.
