I just installed a nice little tool called Snap Shots. It basically gives you a preview of each link without you having to visit that site. So you can decide if you want to go to that site or not. I am not sure I like it myself as it is rather a big window that opens with the preview. But you can turn it on and off.
Just click the Options icon (the thing that looks like a cog) in the upper right corner of the Snap Shot window and click Disable for this site (or for all sites on the internet).

Update: removed it again. Was irritating the hell out of me!
