Increasing hidden TABs puts a heavy load on firefox. If you reduce the number of hidden TABs, firefox will run very fast.

I use TAB group switching, bookmark folder import and export. Sometimes delete groups.

Can you add an interface to your add-on that makes it easy to import and export bookmark groups?

This addon has become a vital part of my firefox usage. I can even say it's one of the reasons I'm using firefox and also recommend firefox to others. I hate having so many tabs open. I prefer logical grouping of the tabs. It's more than a nice to have for me, it's a necessity. Great work.

Auto sorting tabs by keywords is ... I can’t decide if I need it, but it looks interesting.
Installed Firefox Nightly 71 + tab manager Tree Style Tab = while everything is stable.

Below was a complaint about the delay in opening the menu on 'F8' - yes, rarely, but sometimes the menu does not immediately open, or does not open at all.

The addon is nearly perfect and I love the group icons. It`s the best addon I´ve seen to manage tabs. But sadly it`s not working correctly anymore. When I change the group, some of the tabs change the group with me and stay active. Are you aware of this bug (probably from a Firefox update, since before it was running great)? I use Firefox Quantum.

Update: It seems like other Tab Group Addons are having the same problems.

FINNAALLLYYYYYYYYYYYY!!! FOR THE LOVE OF GOD FINALLY FUCKING FINALLY!!! I'VE BEEN LOOKING FOR AN EXTENSION LIKE THIS FOR OVER A FUCKING YEAR SINCE THE UPDATE THAT KILLED THE OLD GROUP TABS. FINALLY A PROPER EXTENSION THAT *HIDES TABAS* INSTEAD OF CLOSING THEM. THANKS MY FRIEND FOR MAKING THIS FUCKING PIECE OF SOFTWARE THIS MADE MY LIFE SO MUCH EASIER I LOVE YOU

This add-on is now completely broken. Tabs opened in or moved to a specific group will show up in all groups, obviating any benefit this add-on might create. Unless this is fixed, the add-on cannot be used anymore. It's probably time for Mozilla to develop a proper tab group replacement for modern FF.

Well until a few weeks ago.

The problem is the auto-backup, the backup no longer saves the tabs (this empty). Therefore, when the add-on is update and loads the last backup there are no more tabs.

I've had to disable auto-backup and restore my tabs manually with my last correct backup (2019-08-26).

Very useful. Thanks!

This is a sad joke:
- it doesn't work if 'Restore previous session' is disabled,
- it doesn't work in private mode.

As it is it's a waste of bits.

There is a bug that if I hit 'F8' or click icon to show up groups view all I get is a little modal. I need to click the icon again to show the groups. It's very annoying.

Simple Tab Groups is "exactly" what I was looking for to replace the old Tab Group Manager! I delayed upgrading from the old version of Firefox for a long time because I didn't want to lose the ability to group tabs. I tried several other tab managers first, but they didn't do what I wanted. STG is very intuitive, very functional, and easy to learn. I can't say enough good things about it! The only thing it lacks, compared to the old Tab Group Manager, is the ability to resize groups in the "Manage Groups" display, but this is a minor issue, and in some ways the ability to scroll down for additional groups is an improvement over Tab Group Manager, which couldn't scroll and would get very crowded with a lot of tabs and groups.

Been using this for a while and it's pretty nice. Recent update said to set the add-on to not work in incognito mode. Fair enough. I changed the setting. All my open tabs were lost immediately. My browser was reverted to the state it was in ~1 month ago. I can't even recover them with recently closed tab or recently closed window. For an extension that's supposed to enable my tab-hoarding, this is a low blow.

It used to work really well, but recently keeps forgetting all my tabs across reboots. It all started at the same time the "incognito mode" warning came. I basically became useless for me now.

Indispensible for me at work & home.
STG and its predecessor are the reason I use FF

The latest versions of STG are deleting my tabs in all tab groups that are secondary windows. I had to revert back to 3.4.4 to fix the problem. On latest firefox v68 working fine on 3.4.4, but 4.0+ has the problem. Great add-on still! Thank you for the backup feature, it's a life saver.

amazing!! wonderfull stuff, thx.

Great addon usefull and I can't work without it. Just a new bug in 4.0.1.2 = the welcome page is fixed now OK but now it's goes always on the first tab on the group instead of going to the last opened tab ... thanks bye

i finally understand the problem. please fix this.

1. "default Tab Groups" is always open
2. i open "work Tab Groups" that have 10 tabs in new window
3. i reload and check 3 of "work Tab Groups" and don't check the others
4. and i close the "work Tab Groups" window
5. when i open "work Tab Groups" window again, only the 3 tab that i checked last time, have links. the other 7 tabs, are null and when i click on them, it opens a blank page!

Endlich eine vernünftige Gruppierung meiner Tabs möglich. Und: Es funktioniert auch alles einwandfrei!
Sehr sehr angenehm. 100 Punkte.
