Exactly what I am looking for!!! I always have like 30+ tabs opened!! This solves my problem. I will see if this can also solve my PC memory issue. Just wondering if the extension actively cleans up those tabs that put into background to release memory ?

Absolute must have for switching work/fun context ;)

I was searching for something like vivaldi tab groups, this is a life saver, and really well organized, even better than vivaldi tab groups

The single most valuable extension available for Firefox. Running Win-10 Pro with a fast processor and 32 GB RAM means having a bunch of groups with 8-12 tabs each is no problem.

Initially, I submitted a review stating that this extension didn't reload tabs in their groups when closing and opening Firefox. It turns out that this was a conflict with the addon Tab Session Manager, which was reloading windows of its own accord. Since disabling that feature, this addon functions perfectly and deserves five stars. It is a great extension.

太棒了，曾经的经典又回来了，又有了重新用firefox的理由了。
Great Addons！this let me from Chrome to Firefox!

This addon is great. Panorama never should've been removed from the browser. I can't think of anything I want it to do that this addon doesn't do already. Maybe fix that bug where closing a tab sometimes takes you to another tab group, but that's a mild annoyance I can easily forgive. Everything else is great and with the latest update, the panorama seems to come up faster and is more responsive.

Отличное расширение для тех, у кого 100 и больше открытых вкладок!

Works like a charm. I'm a freelancer who needs to keep up with multiple projects at once and this has been a life-saver. Bonus points for keeping various messenger tabs (like facebook's workplace or slack) active so I can hear the notification and see what's up in a timely manner. 5*.
