I'm newish to security issues, so be gentle with me.

I bought a digital certificate, and installed it on my TPM chip. I have loaded the relevant PKCS #11 module in Thunderbird; however, the certificate on my TPM chip does not appear in Thunderbird's Certificate Manager. I know that Thunderbird is accessing the PKCS#11 module, because it asks me for my TPM password when I open Certificate Manager.

After reading the posts in this group, I checked that the certificate has a nickname (Yes).

I'm wondering if it could have something to do with certificate purposes: my certificate says that it is intended for "All application policies", but doesn't specifically list e-mail signing as an intended purpose.

I don't have to import the certificate into Thunderbird separately, do I? I mean, it should stay in the TPM, and Thunderbird should be able to see it, right?

I dunno; I'm lost. Any ideas where I should start looking for a cause?

Dave
