I love the new Firefox profiles, but they're missing one key feature for Firefox to completely replace my current "Chrome for work stuff, Firefox for personal" setup on my work laptop. I'm on macOS, and I switch a lot between applications with Cmd+Space. Right now, I can switch between them easily because they have distinct window names. If I switch to Firefox profiles (one "Work", one "Personal"), I lose that right now because both windows are called "Firefox". If the profile name got added in any way to the window title (e.g. "Firefox (Work)") I could keep switching between them easily, and happily ditch Firefox for Chrome for my work profile.
