I've been bugged by this for a while now, and finally tracked down why the middle click on my linux machine would open tabs, but not close them...
By default, middle clicking on a tab will load whatever is in the clipboard as if it were a URL. To fix it, you just have to go into Firefox's config (type <code>about:config</code> in the location bar, then find the preference labeled <code>middlemouse.contentLoadURL</code>, right-click on it and select the Toggle option to set it to false.
That's it! Hopefully this will help somebody else out...although it's quite possible that everyone aside from me already knew about it

I've discovered that a month ago after some time driving me nuts that strange behavior of middle click.
I really understand you

The extention Tab Mix Plus also has an option to disable this feature of firefox and go back to middle-click-close, amongst other tab-related features. Handy lil' doodad, it is.

Ah, that's nice. I don't know how many times that damn middle mousebutton-click has annoyed the hell out of me. Thanks!
