Die Installation war sehr schwierig für mich: dabei war Homebrew bereits installiert; aber es gab immer wieder Fehlermeldungen im Terminal. Puh.
Am Ende musste ich feststellen, dass nicht wirklich das Profil gewechselt wird, sondern eine neue Instanz von Firefox startet: das hätte ich einfacher haben können – einfach Firefox mehrere Male kopieren; so hatte ich es vorher.
Trotzdem bewundere ich die Arbeit der ProgrammiererInnen.

Brings the best feature of Chromium into Firefox and works perfectly.

You're the real MVP. Cool UI, great job.

Won't execute. Warning setup incomplete

The extension dont work in the Mac

Just what I needed to make me switch from Chrome. Works fine on M1 Mac but setup instructions work fine, as long as you read them carefully. I missed needing to link the brew-installed code to Firefox. Once I did that, everything worked great. My requests for enhancements are small: the ability to color the menu bar based on selected profile and the ability for user-uploaded profile icons.

Overall this is just a great addition to Firefox, which I haven't used in decades but am thinking of returning to because Chrome has become so, how to say it, greedy.

Thanks, @nulldev. Really appreciate the effort.

This addon must be included by default in firefox like chromium profile.

It's a pretty cool extension, I believe the only one of its kind. I would give it a 5 star rating if it changed the icon of the program when you do alt-tab to add your profile's icon like it happens in chrome. Thank you!

Great extension!

I'm surprised that this feature is not offered by default in Firefox. Perfect to separate my different web activities. Thanks very much!

Be careful, additional software potentially malware.

Both are open-source, so you are free to check by yourself. I'm not too great at Rust, so I can't confirm anything, but it's always good to be wary.

I'd recommend just using firefox.exe -P for now until the issues are addressed. It's a lot uglier, but it does its job

As a recent convert from several Chromium-based browsers, I'm surprised that Firefox does not have this functionality built into the core browser. But I'm glad this exists.

Awesome

Probably due to Firefox Update. Add-ons no longer work.

I am pleased with this add-on. As noted by a previous reviewer, I would like to have the ability to password protect the different profiles.

Works, but is quite difficult to set up on mac os.
