Not working. Also requires third party software

Works alright BUT you need a bit of tinkering. Basically, Firefox already has support for profiles. The problem is, you have to go on "about:profiles" and this is NOT user friendly at all. This extension make it so that you have an easy access to these profiles à-la Google Chrome. The catch though, is that you have to follow the little wizard provided by the extension once installed. The wizard makes you install a little program needed for the extension to actually work, otherwise you would see your profiles but clicking on them would not work. You have to create a simple config file to provide the right path to Firefox executable and voilà. Works wonder after that.

The add-on is outdated but I have good news for you. Firefox announced that Profile Management System will soon be added to the Firefox Browser.

guys, you dont need this:

go to about:config in address bar
type browser.profiles.enabled to true.
it works as you expect natively

outdated from 2022

This mod requires installing a 3rd party binary. This is an enormous security risk and absurd for the given functionality.

Add-On has potential, I understand it worked well before but seems to have issues with working since Firefox 124.0.0. Seems the environment variable was deleted. Some people have had success fixing the issue by setting the path correctly with a config file but not everyone has. Would love to see the dev fix this add-on or Mozilla to implement an official version themselves.

Definitely worth checking out, can't promise it'll work though.

This requires a random binary to be installed on my machine to work (Fedora Linux). It's seemingly open source but of course I need to go through the Rust code to understand what it's doing. Also check that the binary was transparently generated from the published code in the gh pipelines.. not worth the hassle. Nice attempt but the risk aren't worth it. I would've rather it offered me the choice to point to the profile folders instead. Less intrusive and more secure.

Era uma extensão excelente, mas faz alguns meses que parou de funcionar. Tem esse passo a passo pra quem quiser seguir e ter a extensão de volta: github.com/null-dev/firefox-profile-switcher/issues/106#issuecomment-2008582801

This doesn't work- I wish it did, and the lack of this feature is THE ONLY THING standing in my way from converting to Firefox completely. I use 5 chrome profiles actively, and its a game changer for managing projects and tabs, and parts of my life. Ive wanted to switch back to firefox for over 5 years also....

Either mozilla, null-dev, or someone else please bring this or something like it to life!

suite aux probleme de fonctionnement et suivant une methode citez ailleur dans les commentaire mais sous windowNoté (par Zein Adi, il y a un an):
sous linux :
dans .config/firefoxprofileswitcher/ ajouter un fichier config.json inserer "browser_binary": "/usr/bin/firefox"} sauvegarder .

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.

Doesn't work. Nothing happens when I click on the different profiles.

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.

Una perdida de tiempo, solo muestra no sirve para cambiar abrir otros perfiles

Only shows the profiles, switching doesn't work.

When the add-on was working, it was ★★★★★. Now it no longer switches when I select a profile. I have to deal with it by starting with "firefox.exe -p" like in the old days.
I then switched to a derivative browser with built-in profile switching.

zero issues so far (using floorp)

This extension does not work for me! I believe I installed the required software after being prompted. The extension displays my profiles, but clicking on another profile does not switch me to that profile.

It doesn't let me switch profiles even with the workaround setting turned on.

Die App lässt sich installieren, aber dann sehe ich das Icon nicht, mit dem ich zwischen Pofilen wechseln kann.
