It doesn't work. I downloaded Firefox, installed the extension, logged in, got Cloudfare 90, then I return to Chedot and it asks me to download Firefox again. I logged into the same account in Chedot as in Firefox. Nothing works. When I try to log in to one of blocked sites, it begins to infinitely "check my browser" and show me capchas. UPD: it works with Facebook, but doesn't work with nnmclub.to. They implemented some anti-DDOS feature. After leaving this browser, as well as Epic Privacy browser, I was able to log in to nnmclub in Chrome with VPN-Professional from Chrome web store.
