How can I open an XPI file extension?
I downloaded cooliris-184.108.40.206949-fx-win.xpi and am unable to install because of the xpi file extension.

Windows doesn't recognize that file type, but Firefox does.
Drag that XPI into the Firefox browser to install it. Or use File > Open File to install it.
