It's a must need, works perfect, good job!

It may by my particular experience by trying to import my groups from Panarama Tab Ghroups, but this extension consumed so much memory that turned Firefox unresponsive. The drag & drop functionality is sub par compared to other extensions.

Спасибо за хороший инструмент.
Почему-то в настройках группы не получается настроить захват регуляркой локальных документов по схеме URI file:///
Это вообще возможно?

The recent update causes an issue with new tabs - have to retype what I am trying to do twice in order for it to do what I want (do a goolge search, or go to the website)

That helps: (by rk)
EDIT. For those having similar issues. I think the trick is to open about:config and set closeWindowWithLastTab to false.

Simple and effective.

I tried more group tabs extensions, but this is the best solution for people who were using the old Tab groups manager which worked before Firefox Quantum. Many thanks!
