Excellent

This is a very simple extension which puts a button on the toolbar that reverses (i.e. flips on the Y axis) any video on the page. This works very simply through a style sheet (CSS) which sets the transform attribute of any video elements to a matrix transform flipping the image(s).

The matrix transform seems to have stopped working for me about half a year ago. When clicked the video disappears or becomes transparent. What does still work in Firefox is to perform a rotateY(180deg) transform instead of the matrix transform, e.g. video { transform: rotateY(180deg) } Perhaps the developer will see this and make an update

It works for youtube, but not for my own camera in google meet, which is what I need

How in the world does this work. There are zero instructions????

This also works with Invidious. Great addon!

Edit: it stopped working very recently nooooooooo

super simple no frills, love it

It's great! Thank you Michael Wright!

Good Add-On to get rid of Video flips due to copy right Claims.
