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.

I'd love to see this as the solution to password protect access to profiles.

This is amazing. It is the main feature that I have been wanting in Firefox for ages. It is only missing 2 things, adding the first one will improve my review to 5 stars. Please have this add-on change the icons on the taskbar or dock to match the profile icons so we can quickly tell which Firefox window is which profile when the windows are hidden behind other windows. Also, please add keyboard shortcuts for switching profiles. Great work, I love what you have done with this already.

Extensions works great, although it would be awesome if it had shortcut keys and be able to switch to other profiles only with the keyboard.

Not much to say, but It works. Especially after a small improvement a few weeks ago.

The best!!!!

this should be a recommended Firefox add-on

It's perfect, I was waiting for containers to implement history separation when I remembered profiles existed.. this simplifies using them a lot. I can only suggest a setting to set the default profile (and maybe automate this based on the last closed window profile).
