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

I gave it 5 stars a couple of months ago, but I have to downgrade to 1 star because if you open new tabs this extension doesn't recognize them and if you switch groups it loses the new tabs. Other extensions such as "Panorama View" and "All Tabs Helper" show all the tabs in the group including recently opened ones. If I close FF and reopen it shows all of my tabs including the new ones, but this extension still doesn't show any of recently open tabs. Other than that it works great.

brings back functionality of tab groups

I appreciate the effort of creating this add-on to make up for a lack in FF, but I'm getting a lot of errors with STG.

New groups created randomly with tabs moved in from the groups I set up.
My groups disappearing when I delete these new groups.
Opening in a random group, not the one I was last in.

I looked for a feature/bugfix request link to add these, but couldn't find one.

Thank you, you saved me :)
