This has been something a long time needed. The biggest issue is in overall usability. The process of assigning a tab (especially one already open) needs to be streamlined. Still, it does exactly what it claims to do, and does it well.

Love using this to help keep some semblance of separation between different activities tracking you, especially facebook and amazon. Only thing missing is that it doesn't synchronize across browsers, so I have to re-create the containers and web sites on different machines.

Very useful! Though needs better control of settings and easier ways to open tabs in the desired container, switch containers for a tab, etc.. Clunky to add sites one at a time. And desperately needs more granularity: for example, I want Google Maps to open in a separate container than Google Search.

I love being able to separate my work and personal tabs.

Отлично помогает при необходимости одновременной работы под разными аккаунтами с одним сайтом, нет необходимости выходить из одного аккаунта и заходить под другим. Каждый контейнер хранит собственные куки и изолированное окружение.
И надежно, ни разу не испытывал технических проблем из-за этого аддона.

¡Perfecto!

Why I can't change the current tab to a group... that's the only issue.

Very good addon

Should integrate Containerise (manually add sites to specifice containers) and Temporary Containers functionality.

This is the greatest thing since sliced bread BUT it is still raw and a work-in-progress (IMHO). Some issues that I've encountered include: Container configuration lost inexplicably from time to time, unable to re-arrange the list of containers (come on!), moving website to another default container requires several steps, requires an another extension (i.e., Switch Container) to switch a page to another container (or if it can it requires jumping through hoops I haven't found).

The idea is great, it will have immense benefit to privacy. It is still raw and has rough edges.

It deserves a better Rating, but the issues are super annoying.

Pair this with Cookie AutoDelete, uMatrix and uBlock Origin.

Keep on, keep on!

Great add-on for privacy, especially together with Temporary Containers add-on.

I love the ease and security of using these container tabs. The key is to take the few minutes to find out how they work, set them up so they work for you, and then they're a breeze to use. Thank you, Firefox!

Fantastic idea and works really well. I cannot wait for it to be included in the Firefox base release.

amazing! reason why i haven't switched to chrome because of mozilla's focus on privacy. one star removed because this addon should be syncing in the first place with firefox sync so whenever i access firefox in my other devices, the containers i setup should be synced.

Super useful to keep my data private.

Super pour ne pas être espionné d'un site à l'autre!

Indispensable. I can't imagine going back to a browser without containers. If you have more than one account with almost any provider, the experience is much better with containers. Also, check out the "always open in" feature -- very useful if you use containers for isolating sites like Facebook.

Good & Useful.
Looks like Multi-Account + Tab Groups . & developed by Mozilla make me feel better than thirdparty .

But . If when I use this addon as Tab Groups .
It 's very inconvenient to change which container I want show only.
It will be better has a button on [container list] that I can make one be only show.
& even which 2 or more container to show or hide.
need it not go into the [tab list] to set it hide or show than come out one by one..

Now this addon do good job on Multi-Account .
But the TabHiding function is completely wasted cuz extremely inconvenient to use .

Awesome add on!!
