Hello, I'm having a problem with mailto links. The problem occurs in Org 9.5.5 (running emacs -q) and Org 9.6.6 at least. It did not occur when I used Org 9.4.6.
I do not use Emacs for email (sorry). The documentation states that when browse-url-mailto-function is set to nil, then the setting of browse-url-browse-function will be used. That function is set to browse-url-default-browser in Org 9.5.5, and it is set to browse-url-firefox in my Org 9.6.6. However when browse-url-mailto-function is set to nil and I C-c C-o on a mailto link, I get this message: "Symbol's definition is void: nil" How do I fix this issue? The other types of links I use (http, https, file, info) all work fine. Scott Randby
