Review for QuickDrag by Tenshi-chan
Rated 3 out of 5 stars
It feels lighter when you drag a link and release it, instead of have to right click > open link or middle click. Also the search function is pretty convenient.
But yeah, as a guy mentioned below the image saving function doesn't work with me too, and I'm using Firefox 38.0.1.
