i just found out that firefox finally made profiles easy to use - a first class feature like chrome.

I found out from this techlore video https://youtu.be/dwFSytu_JUw

and even better then chrome, in macos dock bar, each active profile has its own icon

Chrome has had profiles for a long long time, easy to segment accounts/jobs for better isolation (extensions, etc).

Firefox has always had profiles hidden, they were just a super pain in the butt to the point where it wasn't really usable.

Better isolation is great!
