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...
Ok, but why not do both? If the browser supports all needed features, then let the user continue. If not, recommend list of supported browsers with small text at the bottom describing what feature is needed for technical users.
I like that Google is always the one recommending this while also being the one that does some of the most obvious user agent sniffing
I used to work for a web hosting company and have seen so many horror cases that I agree with you that this is what is happening. I also think it's kinda lazy to just say that they won't support what people are using because it's hard. Even 5 - 7 years ago, this was much harder than it is now.
I'm working on an application right now that requires the ability to load and save data to the local file system. Firefox does not allow this, whereas Chrome does. The whole application runs from the local file system, so I don't think there is much of a security issue.
But I actually do is test for the existence of the function to open the save or load dialog. That way, if Firefox does implement it, Firefox will work as well.
the ability to load and save data to the local file system
That sounds like a huge security risk. I'm surprised any browser allows it.
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 its not, at least for me:
Mozilla/5.0 (Android 10; Mobile; rv:122.0) Gecko/122.0 Firefox/122.0
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.
Install a user-agent switcher extension and pretent to be firefox or whatever. It should work.
I tried this a million different which ways a few months ago. Couldn't get Duolingo to accept it. Gave up and haven't been back since
Maybe it wants some opengl or webrtc, which are disabled by default in mull and bromite?
Hey, I don't want to discourage your language learning, but duolingo really sucks as a language learning platform. It honestly doesn't teach you anything about actually using a language.
You might be much better served by using something like babbel, memrise or even better, Rosetta Stone. They are paid options, but well worth the price I think.
We got it for funsies and went through the final Spanish test. We're both fluent speakers, he's native. We were unable to pass the final tests--not because we didn't speak Spanish, but because it was actually a subjective interpretation of what was being said rather than an objective one, btu they treated it like it were objective. Basically you have to learn it THEIR way. As a linguist, this is a big no-no and I walked away.
Rosetta Stone is there under the black flags too.
I would love to switch to something else but I have not found anything that peopme say is good that offers Norwegian. Do you have any suggestions?
The best one is Language Transfer. Completely free (I'm a patron, though) and speaking as someone who has learned five languages aside from English, this is the best system outside of full immersion.
what on gods sake are they doing so special that requires those browsers explicitly
I'm guessing they don't want to test on any other browsers, so it's easier just to say that those aren't supported. Most likely it works on others, you just need to spoof the agent.
This is definitely the case, but I wonder why companies don't add a button, such as "Access website without support", that would get you to the site while clearly telling you that any technical problems (of which, in 99% of cases, there will be none, since all of this seems like supporting Google internet dominance) will be ignored by support.
Sir, this is the internet. Morons will still complain about broken things in public forums even if you make them click through multiple dialogue boxes and popups with warnings in flashing text.
Most likely it works on others, you just need to spoof the agent.
I have both Mull and vanilla Firefox on Android, they use all the same headers (including User-Agent) according to DuckDuckGo's "what's my user agent" tool.
My guess is that the same defaults that makes Mull more private also disables either cookies or scripts that Duolingo expects to be able to use.
They might not actually require them, but simply display this message if some features detection code fails
Your browser isn’t supported because the developer or product manager who put the website together doesn’t know what the fuck they are doing. What could possibly require some cutting edge feature on a language learning website?
Duolingo is not useful anymore anyway due to enshittification. You'd be better off using programs like babbel or pimsleur >!pirate it!<
Duolingo, where your progress can be wiped out without any notice anytime the company wants to change the structure of the language you're learning. Super helpful!
I mean, at least it allows for more than just Chrome. You can do worse.
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.
Duolingo lost me when they decided to do away with user discussions. Can't believe they threw away all that.
