It offers a new way to organize your Firefox, like a Desktop.
Would be nice to set different colors to groups. As a feature ;-)

Excellent!

User-friendly and helpful

I absolutely love this add-on, unfortunately a recent firefox update has made it so enabling this or similar extensions will make it so tabs can no longer be moved around. I hope this one issue is resolved quickly and I can continue using this great add-on.

I've used Panorama for years, at times this was *the* add-on that kept me on Firefox.

good old panorama substitute. works better/smooth than other panorama-like addons, despite being so old.

Indispensable ! Une mise à jour pour enlever le bouton + serait chouette.

One of the most useful browser extensions I have ever used. As a graduate student, this is life-saving. I can organize hundreds of papers and results, label them, and come back to them as needed vs relying purely on a reference program like Endnote to keep track of things and constantly have to re-search everything. Half tempted to credit you in my dissertation!

This add-on is simply amazing, not just an ugly list of tabs (like other add-ons), but an actual preview with all the groups neatly organized, very easy to edit and manage.
