Would be five stars if it wouldn't load every tab at once when switching groups. It kinda lags my PC

This is the best replacement for the original TabGroups extension from Firefox <57. Works very well considering the current restrictions of the Firefox API. I'm looking forward to the day when Firefox allows this extension to hide tabs instad of closing them.

I can not believe that this is the replacement for the old Tab Groups??? I just tried to restore 139 tabs and lost everyone of them. If I had just seen the restore session tab before I tried to use this extension: I would have been fine. I am NOT at all - in no way at all - liking this new Firefox except that it is faster. Yes it most definately is but Most of the fun using Firefox was the addons and extensions. That - by the way - used to work pretty darn well. Now there are Other extensions or Might we Say - No Extensions!

Great extension, lighter and easier than Group tabs.
Is there an option to export tab groups & settings?
Another nice feature would be to be able to reorder groups in pop up window.

Thank you for doing this! It's awesome!! One cool feature would be to have an option to not load all tabs when you change group. That should increase the performance a LOT!

EDIT: The regular expression feature is incredible. Pure sugar for power users.

This extension works well at a brief glance. You can quickly group & sort your tabs and start switching contexts.

Some caveats:
- When loading a group all tabs load at once instead of just the focused tab. It would be nice if the unfocused tabs appeared but did not load, similar to when Firefox loads tabs from last time on start. I suspect this is a limitation in the current WE APIs.
- if there is a tab you want open all the time, you'll have to pin it.

I am happy to finally get back overview of my tabs! :-)

Thank you so much!!

But I'm facing a little problem, unlike the provided screenshots, the extension menu fills some unnecessary space when just 2 groups are in the list as seen in this screenshot: prntscr . com / hmwwxz

Would be great if you could fix it :)

Works great! Thank you! Even like it more than old tab groups!

Great jobs !

I had a shitload of tabs, that was the idea to get something like the old tab groups. I just started sorting out, and wanted to check the new group. When I changed back, it started to load all of my tabs, filling the memory. It wasn't fun.

Neat and convenient, a good alternative for legacy Tab Groups.

Nejen, že to funuje jak má, ale ještě to nalezlo taby ze skupin, které jsem ztratil při aktualizaci FF na Quantum

great thanks to prolongate Tabs group! It's so useful! But there is a big inconvenient for me with this version : when I change of group all my new tabs are refresh... I don't want that at all...
Thanks

Great replacement for the legendary "Tab groups" . Working as intended, the only inconvenience being it loads all the tabs at once, instead of only the active one.
Thank you guys !

Гут!

It brings back old tab groups extension that doesn't work on Firefox Quantum. However needs some improvements. I like working with lots of tabs (currently I have nearly 150 tabs.) When I change first group that has all this tabs, Firefox is running %134 CPU on Ubuntu 16.04. I hope, you can fix that performance problems.

This add-on has saved my life.
