No, that didn't help. I had already set Firefox, Thunderbird and KDE to use Thunderbird as the instructions in the link. Thanks though, for your reply. Wayne

No idea. Setting Thunderbird as the default mail client and setting it up in Firefox as the mailto application worked for me, but I use Mac OS, not Linux.
