Definitely agree! I donโt know how easy it is to implement Material You into apps, but I love the look. This may feed into a conversation that was being discussed last year by @darcese about theming and colorways. I think by adopting Material You, Firefox is seen to be keeping up to date with developments, adapting to new technology and, most importantly staying fresh. Once you get used to curved, translucent apps, everything seems old, even when Firefox is actually kept up to date on a regular cadence.
The icon is a no brainier, no one wants a mismatched icon when all the others are themed. I think the Firefox Nightly app does this, Iโve got it on a Samsung Flip but Iโm not sure if this is a Material You thing or just a Samsung OneUI thatโs doing its own thing and it feels like the latter.
Still not here in 2024. Makes things look very inconsistent with the rest of the system. Which may or may not be what y'all want at Mozilla. If it's not then a "were not going to do this" would be appreciated instead of just keeping it up in the air
