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

Perfect and very helpful! Mozilla is amazing!

Best extension !

Should be embedded by default with some ui refinement maybe...

Muy bueno lo esperaba hace rato. Gracias equipo de Mozilla sigan así que es el mejor navegador!

Это расширение мечты! Сколько лет мы держали несколько браузеров, чтобы не входить/выходить в разные сервисы десятки раз в течение одного дня и вот оно — настоящее удобство! Где же вы были столько лет? Эта идея, казалось, лежала на поверхности… Спасибо!

SIgning in and out of ''multiple'' Gmail accounts. Makes it a breeze now, I love it! Thanks.
