Rated 5 out of 5 stars
The newer Firefox versions seem to gloss over small things that used to work in older browser iterations. For example, when someone bookmarked a site, and in the course of working would bookmark another later on, you simply pressed Ctrl + D, knowing you are saving the url in the same folder as the last time. That's gone now. And this extension restores that and more. Just try it a few times and its value becomes apparent quickly.
That said, I hated the logo. Old, outdated and ugly; that color scheme is neither elegant, cool, or modern, to be honest. I almost didn't install it because of it; it looked like a medieval fantasy icon in a medieval fantasy game ("Q" for quest? lol).
Overall, a fantastic add-on that simply delivers
