Also if you want to prompt what profile to use every time you use firefox just add -P like this "firefox.exe -P" in your shortcut/softlink or script that starts firefox.
It just doesn't have usable profile switching. Sounds like something a competent engineer should be able to implement in a week, yet users have been begging for it for a decade and it's still not there. This is the only thing that holds me on Chrome.
I think his point is that if you have to do about:profiles, then that's not usable for a lot of people. Having something that works like containers is a lot more usable: click, select profile.
See, that's exactly what I'm talking about. Whereas in Chrome I _don't have to_ "try about:profiles".
The very basic requirement for me is this: I want to completely separate my "work" internet from my "personal" internet, yet I also want to be able to easily switch between the two. Firefox makes this unnecessarily difficult and un-ergonomic.
