4.0 seems to have introduced a bug(s) where tabs groups get cleared out when multiple windows are involved.

Using the "restore closed tabs" function when this happens just reopens all the tabs in the current tab group, not their original tab group.

I'll file a real bug report if I can figure out reproduction steps.

This addon has always worked fantastically, and I was really happy with it until the last update (ver. 4.0.0.2) that f*cked everything up.
I DON'T want to restore the previous session automatically every time I start Firefox!!! and I don't want to see the same screen warning me to do so every time I open the browser.
PLEASE REVERT TO THE PREVIOUS VERSION. thank you

Exactly the functionality I wanted to have back from the good old days!

Latest update bricks functionality unless it is disabled in incognito mode. I'm not interested in disabling it in incognito mode; I have been warned, thanks, there appears to be no way to disable the warning. Worked well until now.

When TG was updated automatically to V4.0.0.2 I got the message -
"No support incognito mode, please disable incognito mode for add-on"

I checked the TG add-on option "Don't Allow" for "Run in Private Windows" and restarted FF.

I then got the following page -
"Welcome to Simple Tab Groups v4
Please enable "Restore previous session" in browser settings:"

I checked the box "Restore previous session".

I also noticed that all my tabs disappeared from every tab group. I restored them using a backup and restarted FF.

I again got the following page -

"Welcome to Simple Tab Groups v4
Please enable "Restore previous session" in browser settings:"

even though the "Restore previous session" was already checked.

Every time FF v68.0 starts up, the

"Welcome to Simple Tab Groups v4
Please enable "Restore previous session" in browser settings:"

page is displayed even though the "Restore previous session" box is checked.

I reverted back to v.3.4.4. I have also turned off "automatic update". This is not a good rollout.

Reverted back to Version 3.4.4
It seems version 4.0.0.2 Does not save groups when the firefox option 'Clear history when firefox closes' is enabled.

One of the best add-ons you can get for Firefox! Many customization options, easy to use, fast, reliable, nice UI, good support ... I could go on.

I use it everyday at work to organize my tabs. I am editing pages in Confluence in one window, and open tabs with background information (that I stored in a dedicated tab group) in a separate window in just one mouse-click! I also have tab groups for my different projects.

Highly recommended and many thanks to the developer!

Like others, after today's update I'm getting "No support incognito mode, please disable incognito mode for addon" message and plugin is not working anymore. Been working great, but now I'm stucked in one tab group and hoping that other groups aren't gone. Fix this, pretty please. It was "a-must-have-plugin" until now... :(

UPDATE: after developer's response I was able to make it work again! Thanks! It was pretty easy and I don't understand why I was not able to do it by myself before :D

Please fix this "No support incognito mode, please disable incognito mode for addon" bug. Been working great, then last night it crashed on both my pc's.

I don't use incognito mode, don't have any tabs open in incognito mode.

helps me manage my tabs,
sometimes the functionality is not correct though, a tab is moved when I swap between tabs

thanks Developer

Most useful Tab Manager ever, Keep it alive please!

FF 108 - STG v4.7.2.1

This addon is a replacement for the old abandoned Tab Groups.

The addon works correctly overall.
Its only remaining issues currently are:
- bookmark auto backups. They're a bit messy.. use the hourly file option instead.
- if you open a 2nd window and close the first one, then you'll have to restore from a temp backup.

Its best features for me are the groups manager panel and the quick tab search.

Btw the extension stopped receiving updates 1 year ago. Hopefully it won't break at some point...

OLD VERSIONS

FF v73.0.1 x64 - STG v4.4.25

So far, this version seems to works correctly.
However, there isn't still a "restore from bookmarks" manual button and I haven't dared to try again the "secondary window" problem mentioned below.

FF v69.01 x64 - STG v4.0.62
[..] Sadly it has various problems, like:
- if you close your main window before any secondary one, all your tabs order and pins will be lost! (bug)
- it saves backups periodically but.. it cannot restore from bookmarks! There's only an option from file.
- also, it doesn't clean old sessions.. I had to delete like 2K obsolete bookmarks still there.
- it doesn't save the setting to NOT use a folder for backups. Luckly the bookmark location is ok.
For the rest this extensions works, but it needs an update asap.

Отличный аддон на новый ФФ! А возможно сделать, чтобы после закрытия вкладки НЕ переключалось на другую группу? И по alt-tab тоже. Ужасно бесит, ты альтабнулся и уже другая группа загружается.

If you are switching from Chrome and looking for an alternative to TOBY, this is the one.
I think this should be the first extension that anyone should install as soon as they switch to Firefox.

Excellent. Only reason it doesn't have a 5-star is because not sure how to allow Firefox Sync to also sync this extension. That would be killer!

Update (Aug 6, 2019): Not sure if it's a new release but my tab groups keep getting deleted! Please help.

It does follow the footsteps of Tab Groups of old pretty well. However, when I try to import a Tab Groups backup file, it doesn't do anything. Does anyone know of a solution? If this problem can be solved, the rating will definitely go up!
