Containers have become essential for me, absolutely love this extension.
The only thing missing is support for Firefox Mobile.

Earlier, I would use the Private Browsing feature very often, if I wanted to sign into a different account on a service without signing out of my existing ones. Now, Multi-Account Containers makes it much easier—and I don't even have to re-enter my logins!

Useful for managing multiple sets of logins without having to switch browsers. The "Always open in this container" feature is very helpful: I can make certain websites automatically open in the container I choose. And there's also "Open link in Container Tab" for when I'm clicking on links.

There was a huge need for such and addon and it's great to see Mozilla step up to create it. Way more stable than most add-ons out there and extremely useful.

However, matching new sites with containers should be easier.

Looking forward to more improvements, hopefully, in the future.

Una muy buena extencion la recomiendo

good

Thank you!.
Is very easy and useful the tabs containers

Great plugin to separate work work and personal accounts.

Would give it 5 stars if it let you manage the default domains/containers in one spot without going to each page. Otherwise it's a 3-step process: 1) actually open each page in the right container, 2) check "Always open in ", and 3) when opening the page, click "Don't ask again" to open in the intended container...

I use it constantly to keep my personal/work accounts separated and it works great!

I use this extensively, it works great, and keeps me organized and on track.

I love this extension. I use it a lot. I wish it could be made available in Firefox for Android.

Works okay, but now it asks to "monitor extension usage and manage themes" which seems rather out-of-scope.

This is the best thing since Profiler. One of my biggest concern (or dismay) with FF57 is that my Profiler is now a Legacy add-on. Until I found this. And it works perfectly... for now... until they (FF Developers and Community) decides to make changes again. The Internet (and everything) is (are) always changing... :-)

I really love it

Must have

A solid idea of containerisation, this ensures my cookies of Amazon can't be read by Google for cross-site advertisement. The only missing feature is the ability to synchronise the preferences and customer containers across devices.
