The same chrome extension has more options. What a shame.

dev stopped updating the firefox version and it has been slowly breaking, yet frequently updates the chrome version. will change my review whenever the dev decides to update

Chrome版は更新されているのにFirefox版は何ヶ月も放置されています。
更にYouTubeが新UIになり、当然そちらの対応もされておらず大変見苦しいので代替のアドオンを探した方がいいでしょう。

Well, I have no power to change anything about mozilla review process but it isn't working right now so review goes to 1 untill it does. sorry

Przestał działać. Zamiast video odtwarza tylko dźwięk. Po wyłączeniu wtyczki film odtwarza się normalnie. Konieczna aktualizacja wtyczki!!!

Currently broken. You have to refresh a page after clicking for video window to show up. Will re-rate when fixed.

Unstable needs update. Seems to be abandoned since Nov 2024 (8 months ago). Screenshots are 1/2 1080p size.

A lot of useless functions and at the same time absence of required, like appropriate speed control buttons.

Hopefully it will be updated like the Chrome version. I can't change rows of videos from 3 to 4 etc. It seems very broken at the moment and the Firefox version has been neglected. A shame as this was a fav.

ウインドウの幅を狭くした状態でライブ配信を視聴すると、本来は下側に出てくるチャット欄が表示されない。

More screens are more fun? I disagree. Being able to not see has value to me. I understand that I'm alone on this. Sigh.

Why haven't there been any updates for seven months? Chrome has been on version 3.0.8 for a long time now :|

Sadly it become abandonware, must have addon through the years now breaking and glitching.

the speed is broke

Firefox version has not received updates since November 2024.

The Firefox version is abandoned.

It seems it's broken.

6/17/2025 - extension was working perfectly fine until yesterday for me. now all of a sudden it's not working no matter how many times I try to reload the extension, reload my browser, delete my cache, etc. it's been 7mo since the extension has been updated so that could be an issue. I'll report back if I find a substitute.

Since June, the app has been causing YouTube to malfunction.

terrible

Videos on YouTube lag and play at a low fps since the dev has abandoned this extension.
