Overall helpful, but with a massive flaw in that it randomly moves tabs out of their groups and into the "other tabs" section. Will often do this in the middle of browsing, not even on startup. What's the point of an extension for organizing tabs if it deletes your organization at random? Just a few minutes ago it moved over 60% of my tabs out of their groups and into the "other tabs" section.

I wish I knew this add-on existed before. I cannot do without it anymore. Exactly what I needed, great design, and free!
On of my essential add-on now.

Worst. Extension. Ever. Arbitrarily deletes tabs with no warning and no option for recovery.

This add -on is great but either does not work at all or after some time - this is how it is impossible to work - please improve - help me

Great add-on and a very good organizer. Even better than similar features in Chrome or Edge.

100% CPU usage

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)
