Great extension which enables Gmail and Google Calendar offline sync in Firefox!!

One problem though - for example, if I add the URL mail.google.com as a site to be masked and enter the URL "mail.google.com" in Firefox it works perfectly. However, if the URL has anything after the site name (for example, "mail.google.com/mail/u/0/#inbox" then the extension doesn't work. Please fix that and I will award this extension 5 stars! :-)

Broken. Either the latest Firefox or Youtube changed something. But videos play for a bit and then stop and give an error something went wrong. I disabled Chrome Mask and everything is fine again.

Didn't do much to fix anything, and then yesterday Google decided my browser isn't secure with this addon and logged me out of my gmail and youtube accounts. Only after removing this addon I was able to log back in.

советую включать это расширение в ютубе. вы удивитесь как быстро станет грузится сайт

Great extension that solves the "unsupported browser" problem. Some websites still demand Chrome, and this mask saves the day in a second. Works perfectly without being overloaded with unnecessary settings. Highly recommended!

I don't know how to rate it, I only tried it on Microsoft clipchamp, but it keeps saying that I have an unsupported browser. It wants either chrome or Microsoft edge.

Very useful when needing to bypass those "browser incompatible" error when the site works perfectly fine on Firefox.

great to go though chrome only barriers, but i wanted itto have a auto on toggle.
