A few years ago Firefox had Simple Tabbed Groups (it was wonderful) and then Mozilla changed the Firefox code to be modern/more secure but it ended Add-ons like the old Tabbed Groups. That upset me I lost 4-5 tabbed groups with a total 81 links, just gone. Over the years I looked in the Add-ons for a replacement for Simple Tabbed Groups but nothing until recently. I looked at this Add-on and I said No, it can't be, but yes it is. I do not know if it is the same coder but thank you. I've got 3 groups and growing.

I've just lost all my groups for whatever reason. I'll uninstall...

Well, it accomplishes some things. But like someone else said, when you create a new group, it adds all the open tabs in the window to the new group. You can't remove a tab from a group without closing it. Untill FF comes up with something better, I guess I can use this. But what a pita.

Actually an awesome extension ^^ Managing groups is a breeze, and I love that there are options to play with in case I need a little more granularity. Thanks to the dev for making this possible!

Embarrassingly hard to use, embarrassing that Firefox is unable to accomplish this basic functionality that every other browser has been doing perfectly for years.

If I had to suggests where to start improving this addon: Please don't automatically add every single tab in my window to the newly created group, my tabs aren't organized, that's why I want this app, and please don't close all my tabs when I delete a group, this isn't intuitive.

Not so simple after all. I would love to see grouping like Chrome has it. I can see all my groups in one place (the tab bar). I can read name each group and open each group whenever I want. Super simple.

The Simple Tab Group icon was not visible after installation. I needed to right click Extensions icon, choose Simple Tab Groups settings wheel icon, then pin to toolbar.

Please, add possibility to display icons of all groups in the toolbar at once, as it is implemented in Opera

Now, for use it, you must click 100500 times tom switch between tabgroups

Design become from 1991 year.
Garbage!!!!

Has many bugs that are absolute deal breakers at the moment. It is very easy to loose all the saved tabs.

The best extension for managing multiple tabs out there!

It's good. Some suggestion: Please put the new created group on the top since we want to use the new group frequently.

Overly complicated – too many preferences. Doesn't work as advertised. "Create new group" dumps you in the preferences with no clear way forward. Breaks the "Add-ons and Themes" item under the "Tools" menu. Don't install.

Da ich stänig irgendwelche tabs auf habe, sehr nützlich
