Dear Maxime,

Please update the extension for firefox. It's been so long. I recently learned that this extension is up-to-date on chrome with newer features.

Love everything about this Extension. It is very feature filled and works amazing. it really has change the experience I have had using YouTube and I Highly recommend this Extension to all YouTube Users.
My only only issue is that I would like to see it update to version 3.x like in Chrome. Firefox has version 2.x and fulfills almost all of my needs but i have become accustomed to the certain new features on version 3.x, such as the ability to adjust the number of videos or shorts that are show in each rows and some of the theming abilities.
The extension is worthy of 5 out of 5 stars but I gave it 4 stars because i would like to see the new version 3.x on Firefox instead of 2.x

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.

Great extension the boost volume works wonders, i always wanted something like that to work on my pc as a whole, somehow things sound good on my mobile but not my windows pc even tweaks for youtube extension didn't work like this but this did it in just one click.

I'd like to know what is being used to boost volume? can you please tell me how its done in a way that i can replicate that on my audio equalizer app (Equalizer APO on windows.)so that i can somehow hear things as they should be heard and not have headache to hear things.

I like the app it has those features that can help you at youtube like to make the sound louder or to change the colors. I recommand the extension.

Please update to the same version as Chrome and Edge. This plug-in is really essential.
请更新到与谷歌Chrome浏览器与edge浏览器一样的版本，这个插件必不可少，但是七个月没有更新了

this mod is an absolute essential for me! when it was gone for a few months, i had to make due with a hodgepodge of lesser mods and it was not fun. as of today, though, it seems something has gone a bit wonky because the UI is off center from it's usual and it looks massive and bubbly out of nowhere so it might need a little bit of an update. like, suddenly the icons are in a darker bar and the icons don't fit in it and in fact, the volume booster option is gone. it still works, it's just weird and looks like it shouldn't work

one of my favorite extensions

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 :|

After last YouTube changes (June/July 2025), control elements and keyboard shortcuts stopped working.
UPD: After the last extension update, all works again! 😊
