Since this certificate is for email digital signatures and encryption only, in keeping with the security principle of least privilege, only select the box for validating email. In fact, it is also possible to generate your own keys as your own certificate authority, however such a process is advanced, will cause difficulty with other users being able to use your keys, and is well beyond the scope of this article.
Why must the browser install the certificates to itself?
This part is a bit tricky, because the broader Comodo certificate which validates your email address tips writing articles fceux might not be in your browser! Import the Comodo certificate first and you will see a box which asks what the certificate should be able to validate.
This is important because if you ever have to reinstall Thunderbird or move to a new computer you will not be able to read saved email encrypted with the old certificates if they are not incorporated in the new installation. Even if you should delete a certificate out of Thunderbird, or have to do so in order to resolve a program error message or limitation, make very sure that you back it up export it from Thunderbird first.
To begin, it will perhaps be most helpful if you have a generic idea of the process before we get into the actual details. Once this certificate is imported, you will be able to import the certificate for your email address with no errors and encryption and digital signing will be available.
Export this certificate from you browser and save it to your desktop in two parts.
The point is that your browser already uses certificates, and not only does it use them, it does so without any user interaction.
I should also add a disclaimer at this point that Comodo is not the only CA out there, and I am not necessarily advocating them as a CA above any of the others.
This is not practical for our purposes. Firefox the browser gets certificates from Comodo a Certificate Authority or CA for short but installs them into Firefox. Network administrators customarily will disable a user account of a past employee rather than deleting it because they do not want to lose the ability to access files created with certificates under that account.
It is linked to your email address, and it is the certificate that most instructions sets online are referencing when they describe troubleshooting this process.
We need the certificate to be used in Mozilla Thunderbird, not in Firefox or Seamonkey. As a general rule you do not want to ever delete a certificate in the sense that it is lost and gone forever. So in summary, what we are doing is: Having some grounding in the basics, we will now look at the specific steps which accomplish the summarized steps above.
Instead of signing into your bank or shopping site, what if you had to manually approve or install a certificate to do so every time?
In fact you will be asked to password protect this file when you save it. So far, so good, except that Thunderbird will open the email link in the default browser, and Mozilla Firefox as well as Seamonkey and Opera immediately imports the certificate into the browser and does not give you a chance to save it to disk.
Even if you manage to export your email linked certificate from the browser, Thunderbird may pop an error message that the certificate is not trusted and as a result will not be imported or usable when you attempt to import it because it cannot validate the certificate with Comodo.
Comodo which will generate a certificate for your email address which lasts one year. The solution is to export from your browser and import into Thunderbird not one, but two certificates.

This time there is only one file to save, and for consistency you probably want to save it with a. Even if you do not touch that CD for years to come, you will always have to use the password that you used for that file in order to access it.
Instead, your browser does what it is programmed to do, that is, it imports a certificate when you direct it to one. You do not want anyone to be able to pose as you in such an irrefutable manner.
First start with Comodo. Seamonkey Firefox is a stripped down version of Seamonkey That way when you see the individual steps of the process you will have a better point of reference. Your certificate is validated by Comodo, but the Comodo email validation certificate that is to say the certificate which validates the certificate is also trapped in the browser if it exists at all.
At the same time, Thunderbird cannot retrieve the certificates we need from Comodo by itself. As we can see, there is no readable text in the mail body because Gmail cannot decrypt the message Choose a strong password, this certificate says that all email that it is used with comes from you and only from you.
Now in Thunderbird, import the Comodo certificate first. If one expires, you will no longer be able to use it to encrypt or to digitally sign new emails, but you will want it to read email which were sent before it expired.Blog, libvo_aacenc, Content, Articles.
