On Linux we can middle click the icon on the URL bar to load a URL. However we
cannot perform a search by middle clicking the icon in the search bar. This is
inconsistent. More importantly, there is no one (or two) click way of searching for the contents of the middle-click buffer. So, I whipped together a script to apply my patch.
I'll note that this isn't an extension, it directly patches browser.jar, which isn't recommended. It is also completely pointless on Windows where there is no middle-click buffer. That said, I've used it; I won't wait another release cycle as this bug is constant source of aggravation for me.
