Email attachment won't open. How can I add the file extension to the list that Thunderbird will recognize.

I have a program loaded on my computer that has a file extension of .agl This extension is not listed in those that Thunderbird will open when an attachment is sent to me. The only option is to save the attachment file to my desktop and then open it. Is there a way to add the file extension to the list that Thunderbird will open directly from the email?

Probably not. Thunderbird knows how to open simple text files and some image types. For all others it summons the registered application. That's all I would expect for you; you'd double-click or right-click and Thunderbird would call the relevant program, handing it the attached file to work with. This really isn't very far away from what you're doing at present.

You should be able to set this up under Tools|Options|Attachments|Incoming

In theory you shouldn't need to do this as the OS should handle file associations for you.
