Not store auto-backups

indispensible. i literally won't use FF without it. as a professional developer, i can't understate how useful this addon is for keeping FF in line.

Having over 1,000 – 1,500 tabs opened on my 16GB ram PC for over a year, I find this add-on extremely helpful. Not too infrequently firefox just crashes without showing slowing-down symptom first. Other times disabling this add-on and enabling it a few second afterwards will usually solve the problems without losing any tab groups.
I have one feature to request. Having a dozen windows opened, each with several tab groups, I have on my taskbar a dozen icons with name labels. As it is, the name labels vary reflecting the name of the tab in that window I last visit. It would be more informative if , let’s say, a window contains a lot of tabs about health, the window name label on the taskbar retains and remain the name HEALTH I give for that window. The procedure to request a feature in GITHUB is over my head.

Looks nice, but requires "Access your data for all web sites". It means that the app will have all usernames and passwords entered on a web page. Even the password of my online banking. This is a serious risk we shall all consider!

Excellent extension, exactly what I want. The group switch can be done easily in popup mode. Would be better if the number and name of groups can be stored.

I logged in to tell you that this is a great add-on. Searched for quite some time for specifically this. I love many other features from firefox and other add-ons and without this add-on, firefox was almost a deal breaker. Thanks so much!

Slight User Interface issues like unable to go to a group without selecting a tab from that group.

I also assumed this would save my tabs in addition to organizing them. When I closed Firefox, they all went away. This isn't useful to me.

I like the idea. It doesn't work for me because it only shows icons. I often have multiple tabs open from the same website. These have the same icons.

It helps that tooltips come up, providing the full name of each icon if you hover for a bit. But the hovering takes too long. There isn't an option to speed it up.

One fix would be to provide a toggle that would display tab names (ideally, user-editable names) along with icons. Another would be to display tab names automatically when there's more than one from the same website.

Been using this extension more than two years this point and I can't live without it. Panorama Tab Groups makes tab management easy and enables me to keep hundreds of tabs open for different topics I might or might not revisit later

A simple, well executed implementation of the original Mozilla idea. No fancy animations or tricks but still pleasing to look at in a functional kind of way. Reacts pretty much exactly as you would expect with resizing, drag-and-drop, etc. Very light on resources which is a definite plus. A keeper.

I had something about 40 pinned tabs and I was looking for an add-on to categorize and manage them. After closing a group of 2 new tabs, ALL pinned tabs was closed in a second. So I removed this add-on immediately.

Still has the same problem it had when I used it ages ago, which is that if you right click on one or more tabs to move them to a new group, the tab you're currently on will not move, and after that it won't move even if you click away from that tab and try again.

The user interface is also a bit finicky.
