This is the best replacement for the original TabGroups extension from Firefox <57. Works very well considering the current restrictions of the Firefox API. I'm looking forward to the day when Firefox allows this extension to hide tabs instad of closing them.

Thank you for doing this! It's awesome!! One cool feature would be to have an option to not load all tabs when you change group. That should increase the performance a LOT!

EDIT: The regular expression feature is incredible. Pure sugar for power users.

I am happy to finally get back overview of my tabs! :-)

Thank you so much!!

But I'm facing a little problem, unlike the provided screenshots, the extension menu fills some unnecessary space when just 2 groups are in the list as seen in this screenshot: prntscr . com / hmwwxz

Would be great if you could fix it :)

Works great! Thank you! Even like it more than old tab groups!

Great jobs !

Neat and convenient, a good alternative for legacy Tab Groups.

Nejen, že to funuje jak má, ale ještě to nalezlo taby ze skupin, které jsem ztratil při aktualizaci FF na Quantum

Great replacement for the legendary "Tab groups" . Working as intended, the only inconvenience being it loads all the tabs at once, instead of only the active one.
Thank you guys !

Гут!

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.
