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.
This could almost be funny if the reverse side said something like “He’s too heavy for me”. Even then, it would only work because you’re expecting a “haha marriage bad” reference.
I don’t eat at many expensive restaurants, but that plating reminds me of watching the old Japanese Iron Chef episodes, and how 90’s the food presentation is. Sometimes I look at the (probably delicious) dishes made on that show, and the presentation looks as unappetizing as a 1960’s salad jello. I lack the right words as a culinary critic, but this style seems like “what people 30-40 years ago expected fancy food to look like”.
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.
