works fine in Fx 3.6.3 if you create chrome.manifest in root of extension and change maxVersion in install.rdf from 2.0 to 3.6.* using a file archiver, like 7-zip.
why create chrome.manifest? contents.rdf manifest format is no longer supported at all starting with Gecko 1.9.2; add-ons already installed using this format
will continue to work but can no longer be installed.

chrome.manifest:
