Does exactly what it's meant to do. Great addon for protection against cross site tracking.

Using this plugin is much better and easier than creating profiles in Firefox manually, because instead of having to open a new window for each profile, with this plugin you can view different profiles in a single window.

This greatly minimizes memory usage (up to 5 times less).

Browsing between profiles is much more intuitive and organized, as you can distinguish each profile by the color of the tab and identify the name of the profile that is displayed in the navigation bar.

This plugin is without a doubt the best profile manager currently available in all browsers I have used.

I've been using containers since they first came out. I totally love this. I can isolate my banking and financial activity on a Banking container tab, and keep my work activity kept inside a Work container tab. Nice.

The only thing I'd been wishing for was that I could have a default tab assigned for when I open up Firefox.

The beauty of this add-on, is that I can assign containers to specific websites, and every time it comes up, I no longer have to click on a URL then either move the URL to a container tab already opened (default is no container), or open FF and open a container tab, then paste in the URL.

Now, when I go to a bookmark, it's one & done. You even will get a message for one you've recently assigned a tab, asking you if you want that to be the default tab for it. Perfect. Highly recommend this as well.

Best app ever crated for a browser, I can have separate profiles and run only one app for that. Firefox is truly the best browser, and this extension is probe of it. Thank you guys!

I really like this addon and use it for two use cases: 1. multi-account usage and 2. privacy protection
I don't need to explain the first point - that should be clear.
I have tested the 2nd point thoroughly and can confirm the following: It works.
- to lazy to write examples - so test it on your machine ;-)
