It's good extension but when it has big bug: sometimes tabs in one of the group are duplicated during browser restart.
Update: very stupid and annoying bug, I did reopened the browser 6-7 times and now I have 100 tabs in my Work group. It's so buggy. Can't use it anymore.

This extension is great. It is just the feature I needed for administering my tabs. However, I have the problem I want to have a tab with music in a differeng tab group but when I switch to another tab group the music tab automatically is muted. Do you know how to avoid that?

Outstanding extension for saving tabs! Simple Tab Groups makes it extremely easy to save tabs, while also organizing them to your liking. If you're using Firefox, this extension is a MUST HAVE.

I was really happy with this add-on but for a few days, it detroys Firefox. Incredibly buggy and makes FF work like a snail. Need some work I guess.

Convenient, until it isn't. Duplicating tabs even after full reinstall, suddenly I had 190 tabs out of 19 in one group, and this happened in several groups. No idea why or how, but it makes it almost unusable.

EDITED REVIEW: Breaks Multi-Account Containers (github issue 990), potentially massive security issue, especialliy since broken tabs report insecure connectivity to source. PREVIOUS REVIEW: I think it is great, and it is so nice to have my tab groups back. I would like a couple of options regarding UX but I can raise those separately in the github, I am sure, but the main one of those is an option that when you tap a group it opens in a new Window. Otherwise, once you have it setup to work how you like (I advise no 'auto' creation) it is a silent system winner, and great for productivity as you can silence different workflows and come back to them as if you never left. Unlike chromium tab groups which are always there, staring at you ;-).

Works great, never lose a Group. like other plugins.. Only 4 Stars: Missing a Tree structure. Wich tree-plugin worx seemless with STG..? (in one Sidebar-Tab)

Was very exited to use this extension, but sadly it has been extremely buggy. Tab groups break as soon as the browser is closed and opened. The whole plugin breaks and I had to manually disable and reenable the plugin to get it working, only for it to break when restarting the browser.

Really useful space saving ability to organise interests. I wondered if accumulating so many tabs slowed browser down.So disabled it and deleted them all after doing a json backup. Slow speed is not caused by this so renabled and restored the groups. How to donate or fund the writer?

I use both Mac and Windows, and this add-on is a nice implementation of tab groups on Firefox that feels much like Safari's. The only reason this is short a fifth star is that it doesn't sync with my Firefox accounts on other machines (including my Mac) - so I have to use a workaround. Other than that, I like this.

I LOST ALL OF MY TABS SAVED ON STG GROUPS!!! AFTER SHOW THIS MSG... :((

Database error in Simple Tab Groups
Unfortunately, an error occurred while reading data from the STG addon from the Firefox database. At the moment, the addon is stopped. To resume the add-on, do the following:
Restart Firefox Browser (for Linux and Mac OS with process termination)
If you see this window again, try reinstalling the addon:

Remove STG Addon
Restart Firefox Browser
Install STG Addon
Restore the latest STG addon data backup located in the Firefox downloads folder "STG-backups".
You can restore backup in addon settings

wish there was a way to view all groups at once
unless there is and i'm just dumb. though it is kind of a hassle to open/change groups since it seems more complicated than chrome's 'just click to show/hide'

works great and has helped a lot, can it be available for chrome or edge? i tried loading the unzipped folder but since its an add on, .yml cant be added to either of the other two.
