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.

Пока что лучший аналог Tab groups! Про минусы API с перезагрузкой всех вкладок при смене группы понял, буду ждать изменений. Еще бы хотелось увидеть возможность управлять группами в окне интерфейса как в Tab Groups. Есть возможность реализовать подобное? Ну, и русский в настройках тоже бы не помешал.
Но в любом случае спасибо, не переходил на Квантум только из-за Tab groups, теперь увидел свет в конце тоннеля!

Nice Replacement. Thank you! Importing groups from old "Tab Groups" gave error (do not remember) but groups were loaded after browser restart. Only issue: some tabs were multiple. So I have to delete them manually...
I give 5 stars because it seems that functionality of ald Add-On will be established soon :) Especially sort groups via drag&drop would be nice instead of "move up/down".
One question: my system crashed and after restart all tab groups were gone :( How to backup groups?

Спасибо за оперативное обновление для FF 57. Я надеюсь вы все доделаете и превзойдёте TabGroup. Немного не хватает обновления только последней вкладки в группе при открытии группы, подождём. Спасибо

I'm a librarian and I have to put in a few hours on the virtual reference desk. We use RefChat. When I need to move to another tab group i get a message asking if I want to leave or stay on the page. If I choose leave it logs me out of RefChat. If I choose Stay it opens another instance of RefChat on the new tab group. It does the same thing with our Help Desk software. I'm using Firefox 57.0.

Love this add-on...I can't live without it...

The best tab groups add-on, thank you!

The basic idea of this Add-on is really great!!!

There are unfortunately a few things that make it kind of unusable for my purpose. For example that all tabs in a group have to be reloaded when switching between groups. That really slows down the browser if you have groups with lots of youtube videos in it. Another issue is that a video/music playing tab will be stopped if I switch to another group.

Is there something planned to overcome this problems in the future?

I would love to leave feedback/ideas to make this Add-on even more awesome if you guys are interested :)

Awesome! Though I'd prefer the more visual style from the old Tab Groups, this extension really does what we need.

Wow, this is THE BEST tab manager for 57 right now. Cannot recommend enough. It's already starting to completely replace the old Tab Groups plugin feature-by-feature - even includes option to import old settings from that plugin!

I had been dying inside for this.

Great job!

UPDATE: 03/11/2019
Thank you so much for adding group-sorting options and fast switching! I have, at last, fully migrated to this add-on from Firefox Multi-Account Containers for group sorting alone. Got tired of waiting years for something so simple–yet you implemented it right away! Love the customization options for groups–colors, icons, etc. And it works great with Tab Suspender to save memory. Upped to five stars!

Latest Suggestions:
• I love how one group is shown at a time. On the other hand, it would be nifty to have the option to show more than one group at a time.
• It would be great if there were symbol options for the group-switching icon similar to Firefox Containers to easily identify the group selected.
• When moving a tab to another group, one must first click within the web page of the tab being moved. It would be nice if it would work when just clicking the tab.

ORIGINAL REVIEW:
Finally, a comparable replacement for Tab Groups! It appears to make due without the tab-hiding API by closing tabs (rather than hiding them) when switching groups. This is what I have been waiting for.

Suggestions / Requests
• Please add a way to reorder and sort tab groups by name in group list.
• Please show the name of the currently-selected group next to the add-on icon.

This is great, just what I needed as I was lost without my tab groups an the import worked well. I would like to see the option to reorder the groups in the drop down menu, either alphabetically or drag and drop so that my most frequently used groups are near the top. Also to have the ability to open a group in a new window.

Add-on works nicely. I also imported from "tab groups" backup and it worked.
Thanks!

There are 3 things I would be happy if you added:

1. A simple way to move tabs between groups.
2. Don't load all tabs when opening a group. Only open tab when selected.
3. Manage tab groups and tabs in a overview window.

Edit:
These things exist now. Great add-on!
Thanks!

Works like a charm, author keeps improving it.
Not sure if possible with the new API, experience would be cleaner if it didn't reload tabs on switching (but kept them in memory)

Спасибо за дополнение, отлично работает в FF57, не совсем понятно только почему оно не вначале рейтинга, наткнулся случайно. Из пожеланий, не мешало бы импорт добавить из старого аддона Tab Groups quicksaver-a и будет вообще вещь!!

Very Useful and promising addon.

Лучшая замена старому сломавшемуся Tab Groups.


The best replacement for Tab Groups.
Do you add the ability to drag and drop tabs from one group to another?

Macht einfach was es soll.
It just works. Great!
