This add-on is useful for memory management and organizing the endless collection of tabs I seem to keep open.

I look forward to how the developers can make these easier to use and organize. Certain aspects about the implementation feel clunky to me, but the need is real.

5.0.1: the only lacking feature I can think of is one to move a group of opened tabs to a new window

Would be even more useful if settings (which site to open in which container) would be synced across the devices

Works great. Some irritations - no shortcut to open new tab in specific container. Can't specify the existing web site I'm on to go to a specific container - I have to open the tab container and then reopen the site in that container. Maybe I'm missing something? Would be 5 stars if I could do the above.

It's a great way to keep cookies from different 'worlds' (i.e. work, personal, etc.) apart. Just works, and I've never had issues.

That said, not 5 stars for a few reasons:

1. URL autocomplete is shared between containers
2. Login (username) autocomplete appears to be shared between containers

Good for increasing Privacy/Anonymity online by compartmentalizing tabs into their own little virtual sandbox of sorts.
