Hi Paul, I don't know if it is the best way to do that, but you can: close thunderbird go to: ~/.thunderbird/ there is a directory like ??????.default or other name (your profile folder). There is a file called mimeType.rdf make a backup of it: cp mimeType.rdf mimeType.rdf.backup gedit mimeType.rdf look for some lines like that: <RDF:Description RDF:about="urn:mimetype:externalApplication:application/pdf" NC:prettyName="" NC:path="" /> change to: <RDF:Description RDF:about="urn:mimetype:externalApplication:application/pdf" NC:prettyName="okular" NC:path="/usr/bin/okular" /> save and close gedit, and exit terminal. open thunderbird, and next time you will be prompted to open, you can choose okular and if you want memorize this decision. hope it can help. henrique On Wed, Dec 2, 2009 at 2:26 PM, Paul Smith <phhs80@xxxxxxxxx> wrote: > Dear All, > > I would like to configure Thunderbird to open pdf attachments with > Okular.
