Обновление 0.8.9 стало работать очень быстро! Спасибо!

I have around 300 tabs opened and this add-on is trully a god sent for me!

paired this with a tab discard add-on, I can go even more tabs.

oh and, that Dark theme is really sexy!

I was a little bit afraid when I tried to remove the extension while some of my tabs are in their own groups, I thought they will be gone but they are not. they simply back to a full tabs strip.

so to those who have a bad habit like me, opening too many tabs, this add-on is definitely a must have for you.

Thank you!

Works!
Would be nice to be able to sync the tab groups among multiple devices.

Perfect replacement for Firefox's group tabs feature they had back in version 45.

You are god.

отлично!!! возвращает управление группами вкладок

OMG, tab groups are back in town. Hey, listen. Really. You are doing Firefox great. Thanks a lot! :'D

Ay, dios, tab groups ha vuelto. Ey, escucha. En serio. Estás haciendo Firefox grande. Gracias de corazón.

This add on is very close to how the original Firefox Tab Groups (Panorama) was. The one major feature it's missing is the lack of a "create new Group" option in the "Send To Group" tab context menu item. Currently the send to group context menu item only shows already existing groups and a option to refresh groups, if the Dev adds the "create new group" function then along with Firefox's new multi tab group selecting, we could shift select multiple tabs and then right click and create a new tab group out of them instantly.

Doing perfectly its job! Thumbs up @projectdelphai!
