This add-on is perfect for my needs, I can't find anything as good. The ONLY problem I have with it is that every time I restart, all my tabs get shifted by one degree (so if a link is at the top of a group, it gets moved into the previous group). I have to regularly maintain links in each groups to make sure they get moved back to where they were.

I really like this Add-On for its simplicity and low energy consumption. I had no need for Containers, but the feature does allow me to use them when necessary. The main reason I like this Add-On over others is that it uses Tab Discard based on easy to find, no nonsense Grouping (without containers). Much like have Tree Tabs, OneTab and Multi Containers all in one Add-on. Good job on making something us business professionals and consulting execs need most. Thank you.

Horrible. When I try to organize tabs, the window closes and sends me to the website. It creates copies of tabs when I try to move one tab to a different group.

Clicking on different groups through the header icon does absolutely nothing. I couldn't find a way to simply change groups.
