How do I change the http_user_agent sent by thunderbird when it accesses anything over the web?
When there is an image in an email, which is not encoded but just added as an embedded hyperlink, if I allow the email to display the images, then thunderbird does a GET request to get the images.
Typically, on windows, it uses the default user_agent as the following, for example, on Windows 10: "Mozilla\/5.0 (Windows NT 10.0; WOW64; rv:68.0) Gecko\/20100101 Thunderbird\/68.1.2 Lightning\/68.1.2"
Is there an easy way to change this on my Thunderbird installation on Windows??
