A way to disable middle click searching in firefox?

[Venesectrix]

I use firefox, and I use middle-click to open links in new tabs a lot. The problem is, if you middle-click on something that's not a link (eg, miss the link), firefox instead takes you to a google "I'm Feeling Lucky" search of the last thing you highlighted. Is there a way to disable this, so that middle-clicking on nothing either does nothing or brings up that mouse-autoscroll thing?

It brings up the auto scroll for me. This is version 10. I just installed it on this machine today.

Heck Id prefer it to be the other way around. Id love a google search on any word I click on.

Must be in the options somewhere.
