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:
At the top of the Firefox window, click on the button and then select .At the top of the Firefox window, click on the menu and then select .On the menu bar, click on the menu and select .At the top of the Firefox window, click on the menu and select .
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.
