I would like Firefox for Android to support the Android Themed Icons introduced in Android 12. Having a consistent theming between the apps I use on my home screen determines which apps I use the most and which I prevent using.
This is currently being worked on so we are upgrading the status to "In development"—feel free to track the work here and stay tuned for more updates 😀
Well done @jmarti326 for bringing this up. Good news that this request is now being developed. I would add that Firefox Beta, Firefox Nightly and when Thunderbird for Android is announced, they should also have a Material You icons. Google is putting a lot of work into their interface to make Android the most personal mobile OS and apps that don't adopt this may seen to be less progressive, ultimately harming the brand.
I would love a themed icon as this is the best Android app and it needs to not stand out so badly on my home screen. Any updates on any channels currently using it? I don't mind going up a channel to get it live now.
