Basic functions work: in management mode, drag & drop one tab list item to another group; switch to group. The biggest problem is memory usage after long time usage of Firefox v 143 on a Mac Tahoe (not sure of other OS). The memory usage jumped from around 1GB to 7GB after upgrading MacOS to Tahoe version. In the background, must be keeping other OLD tabs in groups already closed but still open (not sure contents of pages already loaded). When I disabled this extension, suddenly more than 20 tabs popped out when total opened tab in all groups were about 7. Plus, Firefox now has implemented tab grouping feature same as Chrome: to collapse tabs into 1 group tab.

If it is working, it is perfect extension. Unfortunately, it does not load in the sidebar. I have to open another sidebar and then open simpletabgroup again and it will load.

Works as it says, but it keeps downloading files automatically into folders similarly named "STG-backups-FF-137.0.1".
Why does it do this? How do I make it stop?

Add-on suddenly stopped working, which was quite a disappointment.

lately its stopped working and it crashes upon restoring tabs

I tried to perform a backup on one computer and then restore to another. Tabs were moved all around. Eg. All of my amazon tabs were placed in the Amazon group. Even the Amazon tabs that were in my Main group were moved.

Good job, but there are some bugs. Entering Simple Tab Groups Settings removes some tabs, which is a big issue. The dev keeps updating it, so hopefully it gets fixed someday. Thanks!

No icon on toolbar and it is not cleat how to find it :(

I was confused at first, didn't really understand how it worked.

The tabs are basically grouped by window, which is ok i guess but not what i was expecting.

You make a group, and if that group is active then any tab you open in firefox will be added to that group. any tab you close will be removed from the group.

If you activate a different group, your current tabs will be closed (and saved) and the new group tabs will be opened. In other words, you can't have two groups open at once.

It was unintuitive to figure out, but easy to use after figuring it out. However the functionality is not exactly what i want, the tab grouping in chrome is way better than this.

Pratique si on a peu d'onglets et peu de fenêtres. Car au lancement de Firefox il charge la fenêtre courante mais aussi toutes les autres fenêtres "cachées" ou groupe d'onglets. Ce qui ralenti le démarrage de Firefox qui peut utiliser rapidement plusieurs Go de mémoire. Toutes les fenêtres masquées devraient être libérées ou ne pas être chargées dans la mémoire, si on les utilisent pas.

Exemple, 15 groupes d'onglets avec environ 100 onglets au total chez moi.
Chargement de Firefox : en ouvrant une seule fenêtre, 3300 Mo mais c'est surtout le temps de chargement qui est pénalisant.
Avec un autre addon (auto discard tab) je décharge toutes les autres fenêtres, utilisation mémoire tombe à 700Mo c'est plus logique.

😳 like the thought, but convoluted

Well, it accomplishes some things. But like someone else said, when you create a new group, it adds all the open tabs in the window to the new group. You can't remove a tab from a group without closing it. Untill FF comes up with something better, I guess I can use this. But what a pita.

The Simple Tab Group icon was not visible after installation. I needed to right click Extensions icon, choose Simple Tab Groups settings wheel icon, then pin to toolbar.

Sorry, looks like it would help organization but learning curve is too steep. Gave it 30 minutes, then removed.

Yeah, update: I'm out - uninstalling. I cannot stand having to delete the STG folder from my desktop every day I turn my computer on. The bit of good I get from this extension is not worth the hassle.

Pretty good, but ONE MADDENING THING! it covers my desktop with STG-backups-FF folders. Wish I could select someplace these should go. I hate having to toss them daily.

It's also easy to forget STG is there - that's not necessarily a bad thing: it's not intrusive other than the backups. But it's hard to get the value if you forget you have the groups, or go on using your default tab group like it's the only set of tabs available.

Functionally working, but intransparent w.r.t. behavioral details especially when restoring a group.

What is really stupid and borderline insane is the folder-spam where the extension starts to write backups into the download folder. Imagine other applications would do this by default - your download folder would be a crowded mess with thousands of files spamming everywhere.

There's a rare incompatibility with Tree Style Tabs (->TST).
When saving a session in Simple Tab Groups (->STG), the tree structure of TST get lost completely and as a result the stucture is gone.
This happens on :
Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0
OS Linux 6.1.0-7-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.20-2 (2023-04-08)
OS Theme
and is a quite new problem.
Unfortunately I have no real idea how to check, which of both AddOn's produce the "error"...
Does anybody have an idea?
BTW... the rating will be reset after solving the issue, because I know STG since a long time now and used it many times... sometimes in the past though it came to my attention, rhat there were some incompatibilities from time to time - that's why I post this message here and in TST.
