Offers to sync with android, but the extension is not available for android (doesn't appear in search results) therefore impossible to sync with multi account containers on Pixel 7a. Don't know how this will work with multi account containers on my laptop not syncing with my phone

As it says it in the description, it lets you keep different profiles for different use-cases. And helps avoid the cross-site cookies from tracking your activities across multilple sites. e.g. allows you to keep your shopping and social media browsing separated.
While you could do this yourself by managing multiple profiles, this extension simplifies the process and makes it easier to do so.

Add-on is in Russian and it is NOT the language of my OS nor FF. I don't see the option to change the language. It doesn't spark confidence in this add-on in current geopolitical situation.

Terribad sync, messed up everything

It's good to just be good. Pretty cool to also integrate the VPN.

Una extensión muy útil que me permite usar diferentes cuentas bajo la misma ventana y navegador de manera muy cómoda. Es una de las ventajas de Firefox 🦊🙌

Its good, but half baked. Instead of using profiles, we should be able to isolate history within each container and have default container option. Thats the only basic expectation for this extension

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.

Excellent extension! But can it please stop asking (and asking again) for confirmation to open a given web site in its previously defined container, each time Firefox upgrades to a newer version?... That's more than irritating.

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!
