If Thunderbird v38.3.0 portable is closed and I click on an email link I get a pop up window asking me to open a new newsgroup account.
If Thunderbird is open and I click on an email link I get a new message opens with the link address filled in.
How come it doesn't work when Thunderbird is closed?
Running Windows 7 64 bit.
you should better not try to achieve this, as it will break the portabilty
