To enable Mozilla firefox / Mozilla thunderbird add-on that are disabled due to update to newer versions [nightly/daily/beta/new version]

  • Close running applications
  • Open “file_name.xpi” in any zip application [7zip or winrar or file-roller etc.].
  • Open file “install.rdf” in text editor.
  • Find em:maxVersion change to installed version of application like “10a1pre or 10.*”.
  • Update zip archive with modified “install.rdf”.
  • Re-open the application. Check whether add-on working.

If no luck wait till the developer update add-on.
