I was trying to install the DOM inspector and Firebug. Firefox 3.6.3 in OSX 10.5 Leopard. Just to make sure I tried a couple of other plug ins. Each time error 228 comes up. I already tried the fixes in the help with no success.

Try to save the xpi file to the desktop and install the extension via File > Open File. --- http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
