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.

I tested this useful addon on Waterfox , but when i click on the icon i don't see the dropdown menu.
(i read somewhere it's by design but by design of what???)
Edit:
With the help of:

I can see the menu...
Need time to test now!

Excellent Add-on,

I love what your doing with it, but it feels extremely incomplete. I love the product and will keep using it, but there is one thing in particular that really bugs me.

When I have tabs open that are not assigned to a particular container, I should be able to, from that open tab, assign them to their appropriate container.

I can't.

I have to open a new tab already assigned to that container, then travel to that website, and then I can assign that website to a container.

If all tabs are opened in "default" as if it is it's own container, then why can't I interact with "default" like any other container?

Why can't I assign "new tab" to a container?
