Using Thunderbird 38.5.1 on Windows, I sometimes double-click on an attachment in a received message to open it.
The file is saved to my temp directory (
%TEMP%), but I don't want it to be saved to that location (even temporarily). How do I change the directory Thunderbird uses for this?
If there isn't a built-in setting for it, is it possible to somehow override the
TEMP environment variable for Thunderbird only?
