The **Profile Switcher for Firefox** needs a serious update or to be forked, as the GitHub repository hasn’t been modified in two years. With Chromium-based browsers moving to Manifest V3, the need for Firefox customization becomes even more critical. To keep up, Firefox needs to reintroduce the user-switching feature that many are accustomed to from Chromium-based browsers. Currently, Firefox does support:
1. **Casting to Device** , 2. **Making Individual Web-Based Windowed Browsers (SSBs)**
However, **switching between users** is a crucial feature that Firefox lacks right now. Users are seeking this functionality, and if they can’t find it in Firefox or through third-party solutions, they may turn back to Chromium-based browsers. We should not let YouTube and Chromium outpace Firefox in providing essential features like fast user-based switching.

**firefox-profile-switch-connector.exe**

I love the idea behind this app, but unfortunately it didn't work for me. I'm on Firefox on Fedora. Installed the rpm following the instructions and restarted, but clicking on the name of another profile in the plugin's menu didn't do anything.

worked well before but is broken now

It was working fine but recently my clicks have been non responsive. I'm locked out of my other profile and am unable to access any of my bookmarks

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 😖😡

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.

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

fine ui, worked well for me when i installed it, now it prompts me to install the connector software although it is already installed, and is effectively useless.
