A virtual class I was going to be attending was being offered using riverside.fm which specifically only allowed Chrome or Edge, both of which I despise. Found out about this through a reddit comment, installed it, and it worked perfectly. The website ran perfectly fine in Firefox once Chrome Mask got around the stupid gatekeeping. Much appreciated add-on!

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!

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

Great! works like a charm

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

Excellent

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

It works! I used it to play some AI minecraft on oasis.decart.ai

Thanks for the extension. It works well on YouTube.
