It does what it should do and has my respect.

Just like the Chromium profile switcher. Thanks for this amazing tool.

I can't install the .deb file. I'm on a Linux MX distribution, who use the LTS Debian distribution. I'm very exciting to test this extension that I wait for many years...

Very useful extension to handle multiple profiles. Very handy and easy to use. Small suggestion would be "if we an have a facility to upload the profile pic it will be more useful".

Есть мало профилей например 6 то good ⭐.
Нормально работает но для профилей нет ручной сортировки. Сортировка по алфавиту A-Z. 😕
Синхронизации нет!

Если много профилей - нет каталогов и подкаталогов куда можно было поместить профили (удобно сортировать кароче).

1️⃣Лучше юзать "Profile Manager" - Win+R > firefox.exe -P.

2️⃣Если профилей куча то создать ярлыки с путями на конкретный профиль »» https://www.white-windows.ru/kak-sozdat-yarlyk-dlya-opredelennogo-profilya-firefox

Вердикт: вещь абсолютно бесполезная 😖😡

It's really useful for me as I have two different Etsy stores and this is the easiest way to be logged into both rather than having to log out and in all the time. Among other purposes. The main issue I have is that I would really like to be able to use my own images for the icons and there doesn't seem to be a way to do that. It's a minor issue but as someone who likes to customise everything to the hilt it's just one of those things that bothers me whenever I switch profiles.

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
