How to make Firefox extension compatible?

Question

I developed the firefox extension, but firefox (version 3.6.14) says that the extension is not compatible with this version of firefox.

I think mine is install.rdfvalid. It contains

<em:targetApplication>
      <Description>
        <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id> <!-- Firefox -->
        <em:minVersion>3.6.14</em:minVersion>
        <em:maxVersion>4.0.*</em:maxVersion>
      </Description>
 </em:targetApplication>

Any suggestions what could be the problem? What can cause this incompatibility?

Answer 1

I have not tested it, but try to use the format

<em:maxVersion>4.0.0.*</em:maxVersion>

or

<em:maxVersion>4.0.*.*</em:maxVersion>

From https://developer.mozilla.org/en/extension_versioning,_update_and_compatibility :

, * . * maxVersion. minVersion , .
