Could you make the shortcuts customizable please?
Also the "Panorama View" tab should be closed automatically once the overview is left. Otherwise the "PV" tab will be listed in hidden tabs list.

Puh, tab groups is back, very good job so far... I like it

Great for cleaning up dozens of tabs...

This addon replaces Tab groups addon. While Tab groups was like 900KB (almost 1 megabyte) Panorama is only 32 KB. I had to manually enable extensions.webextensions.tabhide.enabled in about:config for it to actually hide tabs, which is the main function.

Thanks a lot <3
I cried for days after Tab Group died... You've made my day !

Using this and Tree Style Tabs means you'll never have trouble keeping your tabs organised, no matter how many hundreds you might want open at any one time. Fantastic add-on, and a worthy successor to pre-Quantum Tab Groups.

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!

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!

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.

Works great as a replacement for the old Tab Groups addon
