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.

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
