Deleting the DigiNotar CA certificate
This article is no longer maintained, so its content might be out of date.
Mozilla has learned that a fraudulent SSL certificate for websites belonging to Google has been issued by DigiNotar. This is not a Firefox-specific issue and the certificate has now been canceled which should protect most people.
You can manually delete this certificate from any version of Firefox with these steps:
- Click the menu button and choose . .
- Click on the panel
- Select the tab
- In the Certificate Manager window, select the tab
- Scroll down to DigiNotar and select the DigiNotar Root CA
- Because the certificate is "built-in" it will be distrusted but not deleted. Distrusting the certificate has the same effect as deleting it.
