I know its not your fault, that Firefox 57 can not hide tabs, but without it its not compareable to the known "tab group" feature. Expl: With this close/reload of all tabs i loose all the states of all open pages and switching between groups needs a lot of time. Lets hope together that Firefox fastly comes around with a working tab hide feature. More about: https://wiki.mozilla.org/WebExtensions/TabHiding

Edit: You are right. I was drove by my bad feelings. Stars up.

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...

Hi there :)
great job with this add-on! The only thing i'm really missing is the ability to let musik play in one group, while i'm active in the other one. Is this possible somehow? Would be great to hear from you ;)

Keep on doing great work buddy

greez, mowgler

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!

This looks like it'll be a good add on when/if tabs can remain open and don't need to be reloaded when switching between tab groups. I, however won't be using this until then.

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.

It's better than nothing, but still a far cry from the original Tab Groups. To prevent repetition, I would like to refer to the comment of J-Dude and hope you will indeed improve this extension, so that it will really be worth using it.
It's a start, but you will need to keep up the good work to increase your number of stars.

Сегодня тестил это расширение. Переключился на новую группу, переключился обратно - а оно заново грузит все 100 вкладок. Я закрыл, подумав, что всё загрузится по клику в отдельности, но получил пустые страницы. Хорошо ещё, что все они сохранились в истории, но увы, вперемешку.
Тут увидел, что в расширении можно импортировать настройки из старого Tab Groups. Но я не могу найти файл настроек в поиске. Как это сделать? Хорошо бы инструкцию для импорта.

Works as expected, only thing I would like to see as mentioned in other reviews, is the option that pages do not have to reload until clicked, or that they are cached and don't have to reload.

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!

I look forward to when this can handle my everyday use as tab groups did. Right now it does not do what I need. I cannot easily move tabs between groups, cannot name my groups, and when I select another group I have to wait for all the tabs to reload which really slows things down. Also, if I have music going in a tab and I switch groups, the music stops. So right now it's a no-go for me, but I'm hopeful for the future of this Add-on cause I'm really missing tab groups since the Firefox Update.

This is what I wanted but it will great if you change the behavior to open only activated tab instead of reopen all when users select a group.

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)

If I move a tab between two windows, the tab didn't auto add in group, until I press create a new tab(ctrl+T).

Спасибо большое за плагин! Отличное начало. Ваша работа дает надежду всему сообществу :-)
Возможно ли в будущем избежать перезагрузки вкладок при смене группы? Или есть техничекие препятствия со стороны новой платформы FF?
