Setting Thunderbird as Default Mail Client in OSX 10.15.6

more options

Trying this again with the recent OS X update - CLOSER!

I recently updated OS X to 10.15.6 and set Thunderbird as the default mail client in OS X Mail and the Thunderbird App. When I select a formatted email address in a document, the Thunderbird mail client opens as expected. However, if I attempt to use the SHARE menu (Photos, Messages, etc), I do not have the option to email the selected item as before when OS X Mail was the default client. If I select MORE to add a SHARE action, the Thunderbird mail app is checked but grayed so it can not be selected. I thought this was supposed to be resolved 10.15.6. Is there more to the configuration?

Last action 7 years ago? I guess we can assume this is low, or NO, priority? Thanks for the info..
