I got this addon a while back to use only a few features of it, but I recently looked at more options and there are A Lot of useful options in here !
If you take the time to look through all the options and use the ones you want it will insanely improve your youtube experience.

10/10, very clean interface, very talented dev

Open Search Results In New Tab (with Ctrl/Shift + Enter combinations) not working. Everything else is fine for the most part.

This is way better than Enhencer for Youtube ! a must !

This is really an awesome extension. I really hope it gains more traction. I also hope it continues to get more features and tweaks. To that end a small feature I'd personally love to see is the ability to set the "interaction zones" tweaks to work during default, full screen, or both. Either way nice extension dude!

Just wow!... I've been using another popular Youtube enhancer (Enhancer for Youtube), which just get so bloated. And now, I try this one and it does just what I need and much more.

The key/mouse binding is just incredible. Now I can map everything to work just as I configured my external video player (SMPlayer under Kubuntu).

Those are a few things that this addon does that the other addon doesn't (that I really like):
- Disable subtitles by default
- Frame-by-frame forward/rewind
- Much more control on fast forward/rewind (I use arrow for frame skip, ctrl-arrow for 3 sec skip, shift-arrow for 10 second skip and alt-arrow for 1 minute skip). Yes, I'm a shortcut-heavy user.
- Comments sorting customization
- And probably a lot more I'll find after playing with it for 5 minutes :-)

memory leaks very much on long videos

Awesome

I was using the enhancer for youtube, but this is superior in every way: less buggy, more options I need, better UI, plays nice with other addons... Great add-on!

Everything works perfectly and the UI is amazing. The dev has done a fantastic job!

thoroughly tested... everything works perfectly! I have used similar add-ons before but they could never deliver everything together. Although the playback speed can use a little fixing since anything above 2x will mute the audio and after setting it on, you can't change it from youtube manually... also a b&w icon would fit with my firefox theme. Nonetheless, this extension will definitely save a lot of my time. Thanks!

don't usually write reviews but this addon does everything i needed.
seek with mouse wheel and volume levelling was all i needed but this gives a lot more.
this is a must have for me now. so glad i found it.

It's good but the fact that you can't use double click as an input or just use the default interaction youtube interaction as a preset makes it some aspects of it worse to use than youtubes' default rather than better.

Is there any way to, after doing a search, going through every video with the arrow keys (up and down)? I'd love that feature. Thank you.

this extension is essential during my YouTube viewing, for tuning the controls using the mouse only. i really like the progress bar and subtitles positioning as well.

I Really like it your add
