Work really nice on Windows 11. Really solve the multi-profile browser problem. But need some installing some .exe extension from github.

For those with FF 124.0 that broke this plugin. Here's how to fix this temporarily:

1. Hit Windows + R.
2. Put "%APPDATA%\nulldev\FirefoxProfileSwitcher\config\" inside the prompt, and hit "ok." This will open the configuration folder. The address should look like this:
C:\Users\[yourusername]\AppData\Roaming\nulldev\FirefoxProfileSwitcher\config
You should see avatar.json and profile-options.json
3. Right click anywhere inside the "config" folder, and create new text document. Name it "config.json".
4. Open config.json (with notepad) and paste the following text into config.json:
{"browser_binary": "C:\\Program Files\\Mozilla Firefox\\firefox.exe"}
5. Save.
6. Reopen FF.

Cool. It works nicely. Firefox should really make this a native feature.

This is exactly what I wanted, thank you!

Great add-on for Firefox. One suggestion I would like get added is password protect for the profiles.

A greate extension, but with 2 caveats, 1st I'm asking to allow adding photos as profile picture. 2nd and I know this might not be your fault, installation process is not easy for normal user, and sometimes it may include defficulties with Xcode on Mac.
Thanks

Thanks for the add-on

Works pretty well. Props to the developer for creating OS specific helper packages so the add-on can run on multiple platforms, including Linux.

just like i what wanted

Thank you!

It does what it should do and has my respect.

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

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".
