Review for QuickDrag by Phyber Optik
Rated 5 out of 5 stars
This feature should be default in FF.
On my top 10 must have's list.
Tiny extension, no-brainer settings and has saved me millions of r-clicks to open links in new tabs and to copy and paste a search term into google.
It has all the features I used to use with Super DragAndGo, and none that I don't want.
