This is not a replacement for Tab Groups as Firefox suggests, this is archaic and can't do a tenth of it feature-wise.

I love it.

Setting all of my work-specific sites to "Open by Default" in the "Work" container is _super_ useful. It helps better separate work and life while still allowing me to use Firefox _everywhere_.

Thanks FF devs!

Using the app to compartmentalise social media networks and media browsing. Super easy and intuitive to use - hats off to the team that built this :)

Ok

It helps me organizing what I am doing by allowing me to add colorful tabs with customized symbols.

It also seem to divide the cookies in between the tabs.
I do believe it works because if an email account is open in a tab with a color, it does not open in another tab with different color.

However, when deleting cookies, cookies of all tabs are deleted all together.

Das Addon macht genau das, was es verspricht. Trennt die Surf-Umgebungen in einem Firefox.

I'm a software developer and I need to login into the same site using several accounts at the same time. Before I was using several browsers - super inconvenient. I love this add-on! Keep it up!

works well

From a technical point of view everything works great. I never had any issues.

From a user experience point of view, I love it. I use it to log into various Office 365, JIRA and Amazon Webservices instances for various fields of work: my own start-up and some other freelancer engagements. Since each tab is a separate container, I can sign into the different accounts at the same time. Before, I would use Chrome for one engagement and Firefox for the other.

The add-on is amazing and works seamlessly, and now it feels like an essential for everyday use; but it could still improve, for example, by including more icons, or letting us choose colors from a color picker, instead of a limited set of default colors.

Can't believe it's taken this long for this kind of feature to come to the web. Absolutely must-have feature, kudos Firefox team! Please keep developing it, it's a solid start.

Awesome ! Would it be possible to provide a shortcut to quickly reopen a tab in a container ? through right click, with an optional toolbar button or even embedded in the existing widget at the top right. Thanks !

Amaizing!

Sometimes the scripts of certain pages that are contained in one container are used in the pages of another container making some kind of Cross-Sripting and blocking pages such as Wikia.com and many others. Basically it's because most of sites are interrelated.

As well that when a link is opened from inside a contained page that link is contained either and not independently from that domain containing.

And now it just logs out my accounts that were not in a container and later I tried to log in to them in the default container instead, and actually can´t mark to open them always in the default container.

I would like suggest a feature. It would be better if we can add subdomains like *.wordpress.com, *.blogspot.com to open always as in a specific container.
