Kroppy, you've done all us FF users a great service - THANK YOU! As a long-time user of Tab Folders (and all the various add-ons that worked up until WebExtensions killed all the great add-ons I'd used for years) I was in limbo until I stumbled on TT. You've given us all a way to organize the dozens of tabs and access them easily. And you listened to all of us begging for folders and groups and you built that in, as well.

Now I just need an idiot-level tutorial to figure out how to USE all these marvelous tools...
