This works perfectly and is very intuitive. I hope this was implemented in firefox out of the box.
Thanks for making this add on.

Incredible time saver and open-source too! Simple and effective! Nice work!

A literal time (and effort) saver! If this didn't exist I was just gonna make my own so thanks for getting there first!

I was going mad having to use the mouse for this, this is brilliant thanks!

If you use keyboard shortcuts a lot and are using containers then this add-on is perfect for you.

It's straight forward in its functions and works just as its intended to.

It works great! It's really useful if you like using containers but don't want the hassle of control clicking new tab every time

Very useful and easy to create new tabs based on your containers!

Edit: This is no longer an issue but I want to leave the information up so the developer's reply makes sense. I love this addon.

The shortcut (Ctrl+Shift+1) conflicts with the Kee addon. It would be nice if it were possible to customize the shorctut keys. Otherwise, great addon.

Works perfectly ! Thanks !

Does exactly what it promises to do. Should be merged into the official container addon.
