Really good, works perfectly.

Great add on

I have been using this for some months now and am very happy. I separate containers by work, client and personal and can continue working on all without having to jump windows or using profiles. I have found this to be more user friendly than profiles being used in other browsers.

Works great for keeping accounts separate. I use it for keeping my home and school accounts separate across services.

I'd love for a future update to include support for syncing containers over Firefox Sync (it's annoying to have to re-create my containers on each device I use).

Also, the current interface for opening a new container tab seems kind of clunky. Having to hold down the "+" button is unintuitive and takes too much time (what can I say, I'm impatient). I'd much prefer having multiple "+" icons next to each other for each tab. Perhaps color each button the same as the corresponding container to make it even more intuitive.

Save a lot of worry and cleaning history betweensites.

This is why I stick with Firefox.

Awesome add-on! Love it! Looking forward to "Replace a tab with a container tab" feature, and more shortcut support.

This such a great extension. I only wish I could "Replace a tab with a container tab" instead of reopening.

Works as intended. This makes trolling 100% easier. No longer do I need 7 different browsers to accomplish my tasks.

Great add-on, but I wish there was a way to store container settings across multiple devices. The lack of this feature is the only thing holding it back from a full 5/5.

a little suggestion:
if i place the toolbar button beside tabs (or the original new tab button), could it be aligned to the left?
