I've visited those links before, but neither of them help, my cache is 50MB, (as I have not messed with the default setting). Halp?

See if this works. Try downloading the .xpi file for the add-on, to do that right-click on the installation link and choose "Save link as". Then in the Firefox menus choose "File > Open File" and open the .xpi file that you downloaded. That should install the add-on.
