"maxVersion" of install.rdf not taken into account with Firefox 18.
I got something really strange with my extension (which install a NPAPI plugin). I was used
to update maxVersion property of the install.rdf every time a new major version of Firefox was
Today, I wanted to give a try of installing the extension with a too lower maxVersion value.
I was extremely surprised to see that Firefox accepted it. I was able to drop the maxVersion
value down to "4.*" (lesser it says that Firefox is not compatible).
