Awesome plugin. Thanks for thinking out of the box!

This, combined with Cookie AutoDelete is fanastic. I can keep suspicious sites (and services) isolated from things I care about. With Cookie AutoDelete, cookies I don't want are erased when I close the container. It is a lot like "private browsing" or using Focus on a cell phone / iPad with some advantages. Login cookies can stay alive until I totally close the browser.

Highly, highly recommended.

This app along with the profile options (firefox -P) make the ultimate combination for privacy oriented people.

Keep up the good work Mozilla.

It's one of these things that you didn't know that they exist but now you can't imagine your life without them. It will make you feel pity for your former self. No more logging in multiple browsers to handle multiple accounts on the same domain.

Really useful while developing sites which needs backend and frontend tests with separated cookies, sessions, etc, separated.

It works as intended but it's annoying when I click a link to an outside site and it still opens in the current type of container. The facebook container standalone add-on breaks out of the container when clicking links to an external site, so it's strange that this add-on doesn't have that function.

This is the primary reason for why I prefer Firefox

I used to use seperate browsers for different activities but now Firefox is my only browser. So in many ways, these containers have made my browsing a lot simpler.

The initial version of containers was very limited, but then it's like they took all my feedback and implemented it exactly the way I wanted. It's great for logging into multiple google accounts at one time, while being able to use all their other services seamlessly. You can also create named containers ones which is what I was really missing at first and it is easy to tell which tabs are in which containers.

Responsive design is unavailable in MA Container Tabs

love it

Excellent thing. Like multiple private windows for each aspect of your life. It even makes all your adverts better, because they will know what you want very clearly. This is a beast.

Excellent idea, besides for security/tracking reasons it is very useful to efficiently manage multiple often-conflicting accounts that get on your way when you work (Google accounts, for example).
I would improve the following:
- possibility to reorder the containers
- instead of (or in addition to) long pressing on the '+' it could be nice to have the "top 3" containers inlined as '+' buttons to open a new tab
- perhaps custom icons for the containers? If it works well

I've been using this Add-on for few days now but I already love it if it works in pair with Ghostery it's falwless combo

It does what it says, and this helps immensely on maintaining ones privacy online.
The best enhancement that can be done is the addition of synchronization of my choices, preferences and configurations on this plugin.

Faz o que se proõe a fazer, e isso auxilia imensamente na manutenção de sua privacidade online.
A maior melhoria que pode ser feita é a adição da sincronização das minhas escolhas, preferên e configurações para este plugin.

This add-on is promising, but is useless to me without the ability to sync preferences.
