Hello, I started to experience a problem with Mull and Duolingo (and also bromite) that started about 1 month ago.
Basically Duolingo tells me that my browser is not supported but it worked perfectly fine before. Anyone experienced this issue? I can’t find an issue on mull repo apparently about this specific issue. Dunno if it is something about resisting fingerprint but I wonder why that happens…
Is that a PWA? Firefox used to support it.
It is simply an HTML page with local JavaScript files. Nothing else. It has to run on as many platforms as possible, and be totally isolated from the outside world.
