As an old school user of Firefox's Panorama feature from years ago, this extension is the replacement I've been behind and it takes the tab management experience to a whole new level.

This extension has also replaced my use of bookmarks, which I didn't realize could be tied into my tab management workflows this way. Great secondary side effect.

It's the ultimate organization and productivity tool missing from all browsers and I'm ecstatic that it's on Firefox now!

And Im not exaggerating when I say this extension existing means I can switch to Firefox full time and uninstall all my other browsers.
