The death of Tab Groups was not the end. I see around 6 or 7 Tab Group alternatives. It's a very good feature and shows how shortsighted Mozilla was and proves it's possible even with wonky workarounds.

After months of nothing, Mozilla finally added necessary apis to function just like the original. This is first one to use the new API and it works perfectly like the original.

This addon finally took me to the latest release of Firefox, the 60th! I had been sticking with a old one, Firefox 56, because no available replacements for tab-grouping addons seemed to exist. I am very very grateful that this idea was re-implemented in the newest version of Firefox and would push the developer(s) to improve and refine it more.

Improvements and fixes suggestions as to 25/05/2018:
1. Tab hiding doesn't seem to work quite well. I have switched between two groups using the CTRL+w key and their tabs have been shuffled all together, that is a merge was formed.
2. The Panorama view could be implemented without opening a new tab. That would feel much more tidy.

Addendum #1:
I found a fix to point 1.! Open the preferences page at about:config and look for the extensions.webextensions.tabhide.enabled configuration. Set it to true and let the plugin work as it should.

Addendum #2:
Would you mind adding an auto-backup feature? Too many a time have I crashed my browser and lost all of my tabs. Having no backup at hand, and no way of restoring my previous windows session, I had to start over collecting and organizing my tabs.

awesome!

Amazing plugin! Made me switch to Quantum. Unfortunately was not able to import my tab groups from the legacy 'tabgroup' addon.

excellent. waited so long for a replacement for the native firefox tab groups.

Plugin says keyboard shortcuts can be changed starting firefox 60. i am on 61 but can't seem to change the shortcut?
ps: the shortcut mentioned in the plugin does not work for me (ctrl+shift+f)
pss: the plugin handles pinned tabs not consistend. i got 2 tabgroups. the first one has my pinned tabs displayed as normal tabs, while the second group doesnt show them at all. i prefer the latter.

Works just like the old TabGroups Add-On and made me switch to quantum!

I just have one problem: I'm currently managing about 700 tabs via Panorama View. Switching the Group does NOT hide all the other tabs, it just scrolls along the 700 tabs, which is unfortunate as it's quite confusing.

Am I doing something wrong or is the option just not there yet?

E: I just enabled extensions.webextensions.tabhide and I'm the happiest man alive. THANK YOU!

Great Addon for new tab group~
1. the icon on toolbar seems bigger than the others . holp to make it smaller & feel uniform.
2. import backup json seems not work all good. i'd failed to backup my tabs.
It's seems only half done & i didnt getting any notice.
3(but not in hurry). it may better has a list when clicking the icon for find my target tab without opening the manager.

-- I prefer Panorama View Cus its simple & it can keep my tabs loading status when i changing the group ( I'd try some like old tabgroup addons. but it must be reload the tabs when change group, even i loaded before..)

-- last . Thx ur addon & wish it better.

This is what I've been waiting for since the old Extension API/Groups was removed. This is amazing!

The only suggestion I can think of is a way of merging some of the functionality between this add-on and the Multi-Account Container add-on.

It works! I finally can group my tabs!

Love this one!
Please, add the posibillity to auto-hide the "Panorama View" tab, as it is avialable in Firefox 61. (The tabis not hiding from tabs list in my FF on Debian GNU/Linux)

I love panorama. The new addon needs a few fixes:

- tab thumbanils
- single click to rename groups
- shortcuts.

Finally getting Tab Groups back. Thanks! Keep working on it and improving it. We all appreciate it

Works perfectly. This is my 3rd updated review, as the developer has been wonderfully responsive and has made some hugely useful improvements to this project. There is only 1 single issue I currently have with this add-on, which if resolved will earn this project 5 stars: For the longest time, I have thought that the "add new group" button was not working, as no matter how many times I clicked it, a new group would not appear! I discovered what was going on. New groups were appearing, but they were appearing BEHIND the groups I already had, so I couldn't see them! When I finally figured out what was going on, I had probably 100 empty groups I had to close. New groups should be brought to the front to prevent issues like this. It would also be great if the feature in the old Tab Groups app of being able to double click on empty space within the groups window would open a new group was added. Otherwise, wonderful job!

The problems of not being able to move or resize the groups is solved. The problem now is that the "Panorama" tab stays open once you close it / hide it with the same Panorama button. See what it is used to open, that you can close the tab later. This tab is hidden in the Firefox environment but is still open in the taskbar.

I'm glad that you made a very nice add-on.
I will ask only one request. I do not want to use keyboard shortcuts, so I want you to provide functions that can be turned on / off.
We support you in the future.

Perfect for when I'm working on projects, being able to organise tabs into thumbnails lets me find them so much quicker.

sometimes extension no longer works after restarting firefox.

Works great as a replacement for the old Tab Groups addon
