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…
I pretty much instantly lose respect for people who design sites to only support specific browsers. With the exception of Firefox, it’s all Chromium anyway so they don’t really need to worry about it. This isn’t like when Internet Explorer was a thing and broke web pages.
i guess it’s not about the actual site not supporting some browser. it’s usually about not wanting to deal with users that have problems with the page in some obscure browser caused by some random plugin or something but the user blaming it on the service. or because of tracking.
So do feature testing, not user-agent sniffing! For Pete’s sake, it’s 2024! That’s been the best practice for decades!
that’s not the point. the user is going to open a ticket because something does not work because their browser does not support it. and it’s way easier to tell them to install ‘this browser’ than to install ‘a browser that supports a specific feature’. most of the users don’t even know what a browser is…
Mull should say its Firefox. What extensions do you have installed?
It reports ESR
Not for me:
Mozilla/5.0 (Android 10; Mobile; rv:122.0) Gecko/122.0 Firefox/122.0
Ok then this is only a Desktop thing
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
Mulls user agent is firefox
It is Firefox ESR
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.
privacy.resistfingerprinting = true
reports the Browser as “Firefox ESR”. Not sure if this even exists on mobile tbh.Added an Extension to my collection to toggle RFP
But for me Duolingo also displayed that after switching my Browser agent to “Chrome 121 Android 14” and also “Firefox 122 Android 14”.
Fuck that app.
