расширение хорошее, но есть пара вещей, которые делают его совершенно бесполезным...
1. невозможно открыть один файл в сохраненной группе, но только всю группу (а если там 20 файлов? вот и приходится открывать всю группу целиком)... крайне неудобно...
2. невозможно ни синхронизировать, ни сохранить эти группы в архиве (что бы в случае переустановки браузера - восстановить вкладки, или синхронизировать с других браузером)...
... вот это и делает это расширение - совершенно бесполезным...

upd как по волшебству на следующее утро после написания претензий открылась (сама по себе) вкладка настроек, где есть опция бэкапа и восстановления всех групп, как видно Санта Клаус прочитал мою жалобу и помог... меняю ради него свою оценку, но вопрос по открытию единственной вкладки из всей группы остается...

I just switched from Chrome to Firefox. The extension that I use most frequently in Chrome is "The Great Suspender". This add-on ("Simple Tab Groups") is even better, since it provides a "Manage groups" page so that I can easily manage and backup all discarded tabs.

Two suggestions:
1) Currently, discarding a tab is a little bit complicated. Is it possible to add a "Discard" button to the right-click menu?

2) It would be better displaying a "blank page" on the discarded tab rather than reloading automatically.

Thanks a lot for developing such a great extension!

How can I copy a group?

I really wanted to love this addon but it's just too stressful to use. As so many others here have already posted, the addon's default behavior of deleting the tabs I've saved into a group is completely at odds with what the addon seems to have been designed to do: group your tabs for opening whenever you want. What's the point of spending the time to create several groups and set them up complete with containers and color-coding if the tabs are just going to disappear? Such a headache. Immediately removed, going back to OneTab.

I was looking for an extension like this. It really helped me out. You don't realize how this helped so much. Thanks a lot!

Worst tab manager ever. Always crash and remove all my saved tabs.

Hi, I love that Addon so much ❤️ - my greatest wish is, that you decide to support the new Safari for the new "MacOS Big Sur" which support extensions like firefox. I will change from FF to Safari when I use MacOS Big Sur in autum. Thank you very much. 🙏🙏🙏

Here some details from Apple:

Can't give this any better rating as the add-on is not intuitive at all. I thought that the purpose is to open several tabs, save those tabs into a group and then reopen them again later. Problem is that as soon as you close the individual tabs they disappear from the group. What good is this add-on if the groups don't keep their list of tabs to reopen them later? There needs to be a tutorial that explains how this is supposed to work.

nice plugin.

This is absolutely my number-one "must have" extension! It replaces the pre-Quantum extension "Tab Groups" with nearly identical function, yet works better and adds more features.

Without this, and a few other must-have extensions, Quantum would be, to me, a non-starter.

If now only the Groups could be stored in folders/ Top-groups that would be very handy regarding the overview.
- like this I have many groups, but cannot devide the frequently used ones from the longterm stored ones.
Also it would be amazing if one could rename the containers and even set up more of them...

Deletes all of your tabs on startup or orphans them at the bottom.

Very comfortable extension for such lovers of 100+ opened tabs, as me. Just group them and save to bookmarks + close unneeded for now groups and later, when you need them you can simply restore from bookmark folder. Love it!
