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!
that firefox profiles are not first class like they are in chrome, but that is moot now, they are just as easy to use now.
