Extremely helpful for web development. Makes it trivial to access the same application with different credentials at the same time.

Amazing. Missing feature to set a start page for Container type

Easy to use - works every time

This add-on alone is a reason to use Firefox

Really usefull extension, I use it every day to separate the activitites I do on internet. The only feature I really miss here is containers ordering. Now I have 8 containers and they seem to be in different order every day, due to synchronization between computers. When I open new tab in specific container, I always have to search, where it is today ...

I use this extension every day! As both a user and a developer, it's soooo helpful being able to keep different accounts logged in on different containers! And it's easy to keep facebook, google, amazon, etc in their own containers so they can't track your other activity. Syncing containers across browsers is awesome too.

The only thing that really bugs me is I'd like to be able to rearrange the sort order of my containers in the menu.
