Earlier, I would use the Private Browsing feature very often, if I wanted to sign into a different account on a service without signing out of my existing ones. Now, Multi-Account Containers makes it much easier—and I don't even have to re-enter my logins!

Useful for managing multiple sets of logins without having to switch browsers. The "Always open in this container" feature is very helpful: I can make certain websites automatically open in the container I choose. And there's also "Open link in Container Tab" for when I'm clicking on links.

Una muy buena extencion la recomiendo

good

Thank you!.
Is very easy and useful the tabs containers

I use it constantly to keep my personal/work accounts separated and it works great!

I use this extensively, it works great, and keeps me organized and on track.

This is the best thing since Profiler. One of my biggest concern (or dismay) with FF57 is that my Profiler is now a Legacy add-on. Until I found this. And it works perfectly... for now... until they (FF Developers and Community) decides to make changes again. The Internet (and everything) is (are) always changing... :-)

I really love it

Must have

A solid idea of containerisation, this ensures my cookies of Amazon can't be read by Google for cross-site advertisement. The only missing feature is the ability to synchronise the preferences and customer containers across devices.

Very useful!!

This is fantastic because I can have several windows of google drive or gmail open, logged into different accounts. I wish there was a page (that I could set my default 'new tab' page to) that would let me choose which container I wanted to go into for that tab.

I have been using a lot of private tabs to switch between environments. This addon is so great! It should be integrated into FF directly

Very lovely addon though there are some possible tweaks.

- adding temporarily tabs which doesnt belong to any container and will be deleted after closing the browser.
like opening a link as a contained tab.
- It would be nice to be able to change the order of the categories.
- Also instead the whole domain it would be nice to categorize just specific subdomains or paths e.g. "test.com/news/*"

besides that, as already mentioned very lovely!

Thanks
