I really like to be able to click on links while reading an article but not have to deal with the links until I'm done. I've got enough ADD issues without tabs popping up. So I was very happy to find this reference to making tabs work better (for me, anyway): Firefox: Open diverted links in new background tab instead of new window

It's kind of an adjustment process because FF is relatively "quiet' - the tabs are opening all the way to the right and not grabbing attention. Just the way I've wanted but it's a little unnerving - I'm checking to make sure the tabs did open.

Highly recommended.
