Really great to see this extension, but please please allow the user to select whether or not tabs are closed in the current group when switching to a new group. I would even suggest to make it the default to keep all tabs open when switching since the current system of closing tabs will cause more headache, confusion, and mistakes from your users than any benefit like a lower memory footprint would make up for. It takes 5 seconds to close and re-open FF if you're looking to free up resources.

Great working app. Works fine and provides the missing functionality after the recent switch of app functionality. Great that it also describes the reasons for the required permissions. Still would like to see that 'Access your data for all websites' requirement is removed, this permission just for favicons seems a bit overkill.

im totaly excited having this add-on. it just does what i need. stable, nice, easy to use. i followed the dev from the first day, it had had all of those bugs, growing to a "version" i trust in for my daily shit i want to do with it. thanks guys .. realy appreciate what you've done so far. thanks! happy to support were ever i can...
for the negative comment from jonnoN some days ago:
"Unloads tabs that are not in the active group. Want to listen to music? Too bad! Useless."
--> mate, just pin the tab you want to listen to and it stays active. ... don't rate it bad for that, please

Working good so far. Good replacement. Any chance that at sometime in the future tabs opened in one group will stay open when you switch to another group like they did in pre-Quantum extensions?

Would be better to use tabs.hide() from firefox 59.

I do love this add-on. However, if you are adding this to an already used window with multiple tabs, you should make sure to add ALL current tabs to new groups BEFORE you attempt to switch to a new group. I lost a few hundred tabs and using History, spent two weeks trying to re-find those lost tabs. A good idea for multiple tabs would be an add-on similar to "Copy All Tabs Urls WE" 1.0.4 By Michele Pezza - at least you won't lose your tab's addresses.

Awesome! I was missing Tab Groups.

Awesome!

Would be great if you could add the option to show the group NAME I am in at the moment.

PS
Please also consider to use the Awesomebar special charakters (%,~,#,..) in your search field!
PPS
Invalid tab ID: 788 appears more and more often! Please fix it! We are losing tabs!

I missed old Tab Grups :)

Like bellow, quick change groups is difficult. add-on have a slow response.

Add seems to have a bug, if last tab is a new empty tab is selected, impossible to switch btw groups.

i need to clic another tab to have the possibility to switch.

Other things. Is it possible to add option to don't reload the active tab?
When filters on a site are activated, all is reset like a new visit.

1 star and it's perfect

Tab Group reborn (almost)

Step by step I retrieve "Tab Groups" module's features.
Very useful module, thanks!

needs to be better. not functional enough.

Almost there. I loved the free arrange of groups on the prior version; but I understand it is coming in the future. Best Tab grouping out there, bar none. Easy to see icons, great graphical interface, easy to export. In fact, the reason I delayed updating to the latest Firefox was because Tab Groups was not in place. Now it is.

Great!

It doesn't switch between the tabs but instead closes and reopens the tabs. Every tab on the group is reloaded. You can use https://addons.mozilla.org/firefox/addon/experimental-simple-tab-groups/ from the same developer for proper tab hide/show but its experimental.

I'll give it 3 stars because it works and it is a great addon, but I still can't find one that makes fast switching. I hope they fix it fast! Thanks a lot!

Fast switching still broken. Loading 74 tabs, taking ages. I don't want the tabs loaded even the active one, I can choose which tabs to load. Please fix. or provide proper instructions! Also are they loading from cache? They shouldn't be taking that long!
It just lost 40 out of 46 tabs, and pinned tabs, in 1 group after restarting firefox The list says there are 46 tabs, but only 4 in the drop-down list and the window.- why?.
It just lost tree tab structure, folders, groups and pinned tabs when I closed and re-opened a group. Incompatible with tree tabs - sometimes doesnt preserve Tree Tabs tree structure, never preserves folders or Groups, please fix or make that clear on the download page before people start spending hours setting up.
(It DID preserve tab renaming which is good)

When it works it is very good but these issues are becoming too much! Are you going to fix these and if so WHEN, please?

It seems to randomly create new groups and doesn't save tabs in your current group so that when you change groups and return to your original group lots of tabs have disappeared
