Given the poor state FF API has been in ever since Quantum, this is as good a replacement for Tab Groups as can be expected. There is a rather unfortunate and extremely annoying issue where when you switch to a different group, your current tab moves to the new group, but otherwise it seems to work more or less as well as you could expect. I wish there was an option to close the "group management" tab when you select a tab in it, the way group management worked in tab groups.

very nice

was looking for this add-on for a long time, works as described, good job

Love the new version with tab hiding!

Still one of the best Addons and one of the reasons I still use Firefox!

Thanks to the dev that he understands the needs of the users and keeps the core functionality like it is.

I see that some people give one star because this doesn't work as a library (only open tabs are kept in groups). Please keep it this way!

Thank you!

Great work! I've been missing the old Tab Groups so much and this extension is the perfect substitute. Thank you very much!

Calling it Simple is a bit of misnomer; it's more feature complete than the 'Panorama View' add-ons. Speaking of which has the "free range" aspect that this add-on desires. So with the new update, it acts as a good replacement for like the original "Tab Groups", it's not a perfect 1:1 but that's alright. The issue of tabs loading all at once, or closing are a thing of the past. I've switched back to this and look forward to future developments.

Consider adding Dark theme and DuckDuckGo icon proxy service (example: https://icons.duckduckgo.com/ip2/youtube.com.ico). I'd rather use that over Google s2.

Great to have tab groups back with this extension. Now that the tab hiding API is available and used it's fantastic. Thanks for the excellent work on it!

I was waiting for this update, now the extension is very good! Thank you!

In this version of Firefox 61.0 the tabs are hidden in all the sites except the thumbnails of the Windows taskbar where all the groups of all the groups are shown together. I think it did not happen before. Just fix this so that the extension is perfect and 5*

Edit 1:

Thanks for your response. We hope that later it can be fixed (the thumbnails are very practical).

Another error that I have found is that when closing the last tab of a group, instead of appearing the Newtab page or disappearing this group, the last tab of the previous group is moved there. I've only been able to try it with 2 groups.

Nice legacy Tab Groups replacement on quantum! Most of hotkeys for switching groups can almost recover the legacy one except those limitation in extensions (That's no choice). Good to see this release just before legacy Firefox ESR end of support. Thanks for bringing the final hope and allow for move on quantum seamlessly.

I am looking forward to the free arrange be implemented and that will be fully replace, and/or even enhance of legacy Tab Groups.

Suggestion: Is it possible close the "Manage Groups" tab after switching groups? Otherwise whenever using hotkey to open "Manage Groups", it will switch back to the group with "Manage Groups" tab. The current solution is uncheck 'Open "Manage Groups" in new tab'.

Edit: already in STG 3.0.7, not experimental
Edit 2: Thanks for response. One more suggestion: how about close "Manage Groups" tab when it is inactive OR hide all other tabs when "Manage Groups" is active (so user must choose a group or close it to remain in current group)? This can force the "Manage Groups" tab never belongs to any groups, which prevent group auto switching when opening "Manage Groups".

I like most everything about this EXCEPT for the fact that the tabs reload whenever switching groups. That's very annoying. For example, if I download something in one tab, wait for it to complete, switch to a different tab group, and then switch back, the tab reloads and the file start to download again. That's just one example of the annoying behavior.

If it wasn't for that, I would be satisfied and would stop looking for a better tab manager. As it is, the search continues.

UPDATE: A later version of this fixed the tab reload issue, so now I'm much happier with it.

beim gruppenwechseln, werden immer alle tab neu geladen.. was manchmal nervt

- Il manque la possibilité d’une sauve garde automatique
- il manque la synchronisation des onglets dans les Marques-pages : que chaque groupe soit rassemblé dans un dossier des Marques-pages : "Simple Tab"
- dans le menu-contextuelle depuis "Simple Tabs Groupe" pourvoir arriver directement dans "transféré dans un groupe" et que l'option "définir… … " soit mis dans cette zone. Elle sers trop peu pour être un passage obligatoire.

Update 2022: The new default behavior is to show a menu popup when you click the addon button instead of the "manage groups" overview, and I cannot find a way to switch it back, making this addon much less useful to my workflow.

To the developer: It would be amazing if you could add a toggle in the settings that would make the addon button in the toolbar immediatly open the "manage groups" window instead of opening the popup.


2018: It works wonders, and is a great replacement for the pre-Quantum tab group add-on.

Looks great and works well. Thank you!

Changing groups just closes all your active tabs and opens the others. So when you switch back, all your tabs reload and you lose history (as in the back or forward button). Pretty pointless. It's about as useful as having a text file with links of your tabs, because you lose your history. This add on should take advantage of the new tabhide in the about:config and maybe that will help it work properly.
Also, even though I restore info from the old tab groups, it didnt bring the history so again i cannot hit back button. shame.

It does what I was looking for!

Дерьмо редкостное. Во всяком случае, с версией 60.0.2. Половина вкладок не загружается, добавляется в группы неизвестно что.

The interface, like many WebUI extensions, is pretty horrible. Notifications are extremely slow and take a long time to disappear. It’s almost impossible to move tabs from one group to another with accidentally loading the group. Similarly the group list has two sides: the left side will load the group; the right side will load a tab list of the group. This is not very clear as this behaviour isn’t normal for a drop-down menu.

Loading a group with a large number of tabs (despite the option to only load active tabs) will try to load ALL TABS, potentially freezing your computer. Firefox itself does not do this when loading tabs, so it’s a mystery why this extension does.

Finally the Manage Groups page shows nothing, so no managing is possible.

Addon crashes with Message: TypeError: t is null

Don't forget to implement a simple nullcheck. If(obj != null) very simple

Dear Drive4ik - when you gonna fix the bug - ??? it keeps on giving same "Tab error" still :(
