Hi there,

Thank you for reaching out! I've filed an enhancement request for that: bugzil.la/2000678

Actually I forgot to mention that I use Mac OS Sonoma 14.8.2 (23J126) and I tried creating a new profile through the profile manager, then deleting that new profile and not the original profile. It didn't work.

Yeah, that's actually how it works at the moment. Once you have tried the feature out, you'll have the profile name in your window titles. However, what you can do is renaming the profile, including using an emoji as a name :)

Sadly, it didn't work. This: "Check the window title by pressing Alt+Tab or hovering over the Firefox icon on the taskbar and than hovering over the title." did not work. I do not run on a Windows OS, it's Mac OS. What is the equivalent to this on a Mac OS?

Can you get to the "pencil" button?

I tested a change, and it didn't seem to take effect immediately. I probably need to quit/restart Firefox.
