Templates do not work with "mailto"

[medimurks]

From Thunderbird Version 128 on (tested amongst others with 128.3.3esr) the following issue occurs:

When I start writing a mail via the "+ new message" button from within Thunderbird, SmartTemplate works fine as expected.

But when I start writing a mail via a "mailto" link (e.g. clicking on mailto:github@mic-vat.de in a Word document) then an empty mail opens instead of my template.

Thunderbird version 115.16.2 seems to be the last one where this issue does not occur.

It works for me in Thunderbird 128.3.2esr, can you see what identity Thunderbird selects in the "From" field? This is what triggers the loading of the template.

in this example the identity triggered is based on the email address thunderbirddaily67@gmail.com.

You can test which (and whether a) identity is triggered via debug mode. Open SmartTemplates settings >> advanced settings page. Enable Debug Mode:

Click on the settings wheel to the right, then activate:

extensions.smartTemplate4.debug.functions.insertTemplate = true
extensions.smartTemplate4.debug.identities = true

Open error console (Ctrl+Shift+J), then clear the results. then click a mailto link and wait until composer loads.

You can then capture the debug log (including errors, warnings and Logs) via right-click:

you can send me the log off list if you like.
