If it’s trying to talk to a device over Bluetooth or USB, it’s not supported in Firefox. Mozilla refuses to implement WebUSB because they think the danger of letting people accidentally flash malware onto a physical device outweighs the benefits.
Are you able to independently confirm that the domaincheck container is listening to the right port? Eg netstat -tunlp on the host
I think you’d be hard-pressed to find a LinkedIn alternative. It’s too business-oriented for anyone to care that it’s under corporate control. In some sense, that’s the whole point.
My understanding of Friendica is that it’s supposed to fill a niche similar to Facebook. I’ve never used it though.
Every time my GF Nicole joins a new instance, I make an account on there too. She’s a bit of a fediverse chick.
There are definitely UI inconsistencies across devices, especially smart TVs. Jellyfin on Firestick looks different from Jellyfin on Roku which looks different from Jellyfin on WebOS. Some devices deliver Jellyfin through a thin browser client, and in those cases you get access to a unified design. Outside of that it’s a crapshoot as what the app will let you do. Of course, it’s a volunteer project (and all my thanks to any maniac willing to develop TV apps), so I don’t expect that everything can be easily and neatly unified.
I can’t deny that it’s sometimes hard to support my users because of this. Someone complains that they’re getting movies dubbed in an unwanted language: I can’t guarantee that the button to select audio track will look the same on their end when I talk them through it.
It’s probably using WebView, or whatever it’s called where an android app brings up a browser window. If you have Firefox as your default web browser, apps will use it instead of chrome. It’s usually pretty nice, because if you have adblock in Firefox you also get adblock in the app.
It’s possible that the sign-in webpage wants to talk to the camera before returning control to the app.
