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!!

The reason I didn't give Containers 5 stars is because I can't Clear History per container, but rather have to delete a container and recreate it. Support for removing history per container seems to be already in the WebExtenions API.

After reading a couple of Firefox Multi-Account Containers instructions on on how to use, which I gave a positive Yes if it was helpful, I find I cannot get any website to open in a container. I've use nightly for 5 - 6 months?? I update Nightly almost daily. Gave Firefox testteam permission to install test automatically. Only thing I ever got was the original test version of containers. So installed the production version today. Do not find any right or left mouse button click to provide any accept to open a tab or a new tab in a container. Hold does not work. Spent last 45 minutes with no success. Moving on may attempt again or remove nightly, install production version with containers and see if that works.

Very handy!

Container tabs are wonderful. No more testing with multiple browsers, no more private browsing which share the same cookies! I really enjoy browsing freely on different websites, saving cookies but don't sharing them.

allows me to separate my cookies without worrying about contamination

It should be included by default in every browser. I only wish there was an option to synchronize my config across different computers.

Great idea, with a sleek user-friendly, intuitive execution. I found it easy to open, manage and use different containers. One missing feature that I've felt is the ability to process histories/cache's etc. within each container. e.g. "delete all history from container [shopping], but keep the other container data".
Otherwise, it's a useful add-on that helps users manage and understand their online footprint. Thanks for making it!

This is really great idea man!
