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…
You can try with an extension that changes the user agent of your browser; if you use the one from either firefox or chrome for android it should work. Usually its the only thing checked by sites when identifing browsers for non telemetry reasons; if the problem persists I’m not sure what it could be
Tried and didn’t work…
Then it may be something that mull is blocking to prevent fingerprinting that duolingo doesn’t like, I don’t know how to help in this case other than installing something like fennec in a work profile with shelter; sorry.
Mulls user agent is firefox
It is Firefox ESR
No its not, at least for me:
Mozilla/5.0 (Android 10; Mobile; rv:122.0) Gecko/122.0 Firefox/122.0
No it’s not. Mull is built from the latest version of Firefox for Android, which currently is 122.
Yes but RFP unifies the fingerprint to look like Firefox ESR on Windows.
Not sure about android though, and disabling RFP didnt fix the issue
Afaik all custom FF Android versions use Nightly, but I am not sure about that.
Not on Android. I have it enabled and my user agent is Firefox 122 on Android.
But yes, Mull is built from Firefox Nightly (actually from Fennec Nightly, which removes all proprietary blobs).
