When I middle click anywhere on a page other than a link, it'll take me to a page that I've already been at since opening Firefox, and keep doing it every time I middle-click something that isn't a link. I can't find a pattern as to what page it chooses, and it seems to me like it chooses pages at random intervals and stop after a random amount of time, or sometimes not at all.

Can someone please tell me what's going on, and how I can disable this behavior?

I'm running Firefox 21.0 on Linux Mint 14 with MATE.

It's "pasting" the contents of clipboard as the URL to open.

You can disable it by typing about:config into the location bar, searching for middlemouse.contentLoadURL, and setting it to false.
