I love it. I'm using it to create different areas for my work env. I have stuff to read, docs to follow, and current worspace etc. This extension is excellent, super stable so far.

Exactly what I was looking for. Allows you to load a group of tabs in the current window and flip between groups without any problems. I only wish there was an visual way to identify which groups are currently loaded without clicking on the menu button.

I can't explain how I've survived without this extension before.... This is perfect extension that is helping me on daily browsing, and daily tasks keeping everything organized and handy. It also saves a lot of space on the nav bar. This should be the default approach on Firefox, while it comes to browsing experience, but I am glad that this extension does the job perfectly. Well done Drive4ik and contributors, well done!

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.

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

Very useful. Thanks!

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.
