It seems that nowadays Firefox determines an extension's version compatibility not (solely) based on the install.rdf file that is packaged in the extension (the XPI archive), but some other source (eg. some data from addons.mozilla.org?). I've started going through the install.rdf files of my extensions and found that Nuke Anything Enhanced's install.rdf contains a <em:minVersion>2.0</em:minVersion> and a <em:maxVersion>3.7a1pre</em:maxVersion>. And it works perfectly with my Firefox 4.01. The extension's page at addons.mozilla.org says that it's compatible with Firefox versions ranging from 2.0 to 6.*. If the extension itself does not state this compatibility, then it must come from somewhere else.
