Just what I needed. Thanks <3

This extension is very helpful, I've been using it for YouTube videos when the audio only appears on the left or right.

"My left ear enjoyed this video."
"My right ear enjoyed this video."

I hope this extension will not cause security problems. It works, it works perfectly the position to mono of a video from any page, be it Youtube, TikTok or anywhere else. It works very well.

What I do hope is, that it has no security problems for navigation, I have reviewed the source code from top to bottom, I do not see any problem.

This extension does not exist, nor does it have any external links, nor does it have remote links.

Very useful!
