I really like how well this works and that I'm able to keep my cookies in their own containers.

Very good! But there are some bugs:

If you are in a container, Alt+Enter (in the address bar) should open the url in another tab BUT IN THE SAME CONTAINER as the currently selceted! Currently it opens the new tab in an empty (non assigned) container. This is troublesome specially when the desired new tab depends on the current container (session cookies, etc)

Another bug: If you edit the color of a container while already having open tabs from such container, the color of those tabs doesn't change (but the color of the icon in the address bar does change).

If you open new tabs with the edited container, they do open with the new color. which may lead to confusion having several tabs with the same container but different colors.

Please fix the bugs ASAP. Thanks

This extension is great for keeping your various on-line accounts separated. In the world of multiple Google, Microsoft, etc. accounts, using this extension allows you to be signed in to all of them at the same time (in separate tabs).

I would like to see a few more features around managing the containers - e.g. being able to re-order them to my liking. Also, allowing custom colors and icons.

I would also like the ability to right-click a tab that is open in the "Default" container and switch it to another container.

Finally, adding the ability to sync my container settings across machines would be the icing on the cake :-)

Keep it up!

I'd like to have the ability to sort my list of profiles and the ability to customize start page for each profile... and more icons.

One of the best way to protect your privacy

Great product! Easy to manage different accout on the same web site without closing any.

It works as advertised. However, if you use multiple computers, then you have to go through the setup process for each account on each computer. Either sync through Mozilla Sync or provide the capability to export/import. Dozens of accounts on multiple computers qualifies as a real pain to get the protections this extension provides. Please fix!

Very useful add-on for limiting social media sites' ability to track your online activity.

Easy to understand the usage. Great Add-On.

Works well for me as an end user. I believe this really does keep browsing activity contained. For starters, so far I saw no ads relating to my recent surfing history!

I love how easy it is to use. It would be a full 5 stars if you could convert or reopen a tab in the container. Otherwise, it's a great app.

A must-have / indispensable!

Great way to isolate accounts from each other. The 'always open in container' feature is nice. I do wish you could make shortcuts to new tab containers, though. If you've got work & personal accounts for particular services this is a must-have plugin.

Multiple accounts in one browser. Finally no need to run a separate browser for my work account!

Very useful.

There were some issues earlier like reset back to default containers and loose my options, but it worked well for the last weeks.

**Removed text**, found the feature to list all domains and edit the domain list in the current version. Great!

It is obvious that having silos, or isolated brower sessions per tab is a good idea unless you are fine with being tracked about the web.
This solution for Firefox works well for me, as far as I can tell, and is relatively easy to use. It takes some time to setup and each website you visit belonging to an organization that you want to put into a specific container needs to be placed manually into that container (you can't seem to set a wildcard via the front-facing interface?).
But when done, you just surf and tabs open up naturally and all that you've asked to be isolated is: just as I'd want its functionality to behave.

It's very easy to keep my tabs separated by activity, and I love the feature of being able to login with different accounts in different containers! This is exactly what I needed.

Much more convenient than having multiple Chrome accounts. However, it could be improved. I can't reorder the accounts in the popup menu. There is also a bug where if I open an assigned website from the default new tab "top sites" section, two tabs open instead of one.
