I'm using multi-profiles via about:profiles, however it's difficult to recognise which window belongs to which user profile.

So I'm looking for Firefox add-on which will give me some clear indication on which user profile I'm currently on, by either showing the name of it (similar as in Chrome, in the top-right corner), or by at least by changing the Firefox's app icon.

  • Why don't you use a profile manager addon?

  • @onurcano22 Can you post the link to that add-on? As I'm not clear, as I'm already using Profile Manager which is built-in functionality.

  • Sorry, I guessed there should be some profile manager addons in Firefox site however I couldn't find something compatible with the newest version of Firefox. If you want one for the 2016 version of Firefox: addons.mozilla.org/en-US/firefox/addon/profileswitcher/… and use this addon only if you trust it.

A quick google search for "firefox profile indicator" resulted in a number of links. A couple links told me that the add-on no longer works with my version of Firefox. Yeah, no worries.

One of the more promising links, a github resource, also contained a reference that the system was no longer an optimum solution and was replaced with "containers."

Chasing that lead resulted in a promising add-on for Firefox.

From the linked site:

Firefox Multi-Account Containers lets you keep parts of your online life separated into color-coded tabs that preserve your privacy. Cookies are separated by container, allowing you to use the web with multiple identities or accounts simultaneously.


As settings are supposedly per profile, just choose different themes for each profile.
