THUNDERBIRD | GPO or Registry | Certificate handling



Via Registry:

HKCU\Software\Policies\Mozilla\Thunderbird\Certificates\Install\1 = "mycert.der"


Software\Policies\Mozilla\Thunderbird\Certificates\Install\2 = "\\MYHOST\Users\username\mycert.pem"


Software\Policies\Mozilla\Thunderbird\Certificates\Install\3 = "C:\CERTS\mycert.pem"


If you define only a file name without a path Thunderbird searches


for your files.

Via GPO:

Use the user branch. Define full path file location or file names only.

If you specify only a file name Thunderbird searches



With version 78.3.2 i run into problems importing binary (DER) certificates. I solved this case by using ASCII (PEM) certs.

I debugged this using STRG+SHIFT+J (Developer tools error console).
