Works perfectly for me to control volume of tabs like instagram reels, tiktok, and thread video very easily.

The best ever, no unnecessary features

Thank you very much for this extension. Finally, I can control the volume on YouTube aggain. I must have done something wrong in Firefox because I can no longer control the volume on YouTube for example. The volume slider no longer moves. So I finally have full control again. I find the blue volume bar in combination with the round gray volume control to be a particular color highlight.Thank you very much. Well done. Now, after 8 months of use on YouTube, the VolumeControl extension works just as reliably and well as it did on the first day. I still can't move the volume slider on YouTube, but that doesn't matter because I have this extension. Despite the big changes on YouTube, this extension is still working.
