Send from Finder with Thunderbird as default email

Greetings,

Finder will not open Thunderbird (default email client in System Preferences) to send documents.

Apple Mail crashes repeatedly, therefore, I resort to Thunderbird (works without crashing).

Please instruct me on how to set Thunderbird (already default email client) so that I may send email attachments within Finder. Finder/Share shows Thunderbird's icon, when clicking on the icon, I hear that irritating bird chocking, and Thunderbird does not reply.

Thanks for your reply and help,

Ray Randall
