I outgrew the number of account containers using Simple Tab Groups. This was the best option for 40+ containers.

Quickly search and can even create new containers from the search, much quicker than clicking through the native add-on's UI.

Still working well in 2025, mark of a good applicaiton that doesn't need too much tweaking.

Finally! I was finally able to delete MULTIPLE temporary containers in ONE step, not each individually as with all other add-ons! THANK YOU for this valuable tool!

An incredible extension. Firefox containers are amazing. Mozilla does not even realise how fully amazing they are, so it doesn't really support advanced users due to a small amount of sync space, and also no backup facility. That and so many other annoyances are solved with this extension.

There is magic happening with this add-ons. Mozilla is taking on a new meaning of browser use

Thanks for this...


FYI small bug: the multi-select does not clear. So when multi selecting and deleting containers, when i came back later a bunch of random containers were already selected (seems ~ the same amount i had selected before.)

Excellent plugin. Author is also extremely responsive. Firefox's containers feature is fantastic, but Containers Helper adds enough UI to make the containers a lot more useful.

For example, I have multiple accounts on a few sites, and this plugin makes it very fast to switch between the most important sites/accounts.

I highly recommend opening Preferences and enabling "Opening the current tab URL for containers on the same domain/port/origin"

THANK YOU GOOD LORD THANK YOU SO MUCH.

I've never left a review for an addon in my life but this thing literally saved me so many headaches. When Mozilla added syncing tabs across devices it broke my entire Firefox client. For some reason I discovered EIGHT THOUSAND temporary tabs now listed as permenet tabs. Firefox would crash every time I tried to interact with container in any meaningful way. I tried absolutel everything I could to get rid of them - deleleting all exetension, from every device I have, deleteing every local file, disabling all syncing, resetting Firefox completele....none of it worked. The second I logged into Firefox they all came back. It's bee over a year of this bs.

This extension allowed me to regain control of my broswer. Thank you Chrales, and screw you Mozilla for breaking everything for so long without a fix.

This is perfect for an issue I had where I had around 80 containers that I needed to delete due to previous use of the AWS Console in Multi-Account Containers add-on: http://willthames.github.io/2018/02/28/managing-multiple-aws-consoles-with-multi-account-containers.html

This app save me from temporary container bug ! Thanks you !

Very useful, especially in combination with Temporary Containers and Firefox Sync in multiple compotures - which may create hundreds of temporary containers in the browsers

Just discovered this excellent extension. Super helpful for managing large numbers of containers. I've found it extremely useful to help me book vaccine appointments for senior citizens. Thanks for this super useful module!

Super convenient and user friendly! Just make sure to check the website for quick instructions by clicking on the app on your tool bar and on the blue "Read Me" button to the bottom. This add-on is posted on GitLab so the open source gives me some peace of mind but it would be great if Mozilla did a security check on the add-on to encourage more people to try out this tool.
