Seems YouTube website is not working properly when the extension is on. As I turned it off it works well. Even bring the feature to keep chrome mask on for every website as we don't need to do it manually every time for each and every website. Or else extension is good. I will give you 5 stars once the issue is fixed

Works perfectly, exactly what i had in mind

Works just fine, no complicated configuration needed. Works with a simple slider, out of the box :-) Thanks for this Addon!

This used to be the best way to get around YouTube's Firefox nonsense, but now it's the opposite, YouTube is completely broken when this is enabled for the site. It took me so long to figure out why YouTube barely worked in Firefox anymore, and it turned out this was the culprit. The addon is still great on a bunch of other sites though, so I still recommend it.

perfect for formula 1 tv, since this now blocks firefox, it works instantly after installing this extension. no issues at all with youtube

doesnt work on clipchamp

Great! works like a charm

always up to date to the latest chrome version, not problems so far

I like the ease of use but google still knows its firefox. Same for browser info sites still say its firefox masked as chrome.

Excellent

The fact that it refers to the process as "wearing a mask" makes it 100x better lol
