I have some bogus certificates which I cannot get rid of these say login yahoo ( x 3), mail gmail, google global trustee, when I open them they say bogus yahoo, bogus g mail etc but I cannot delete them from other. They say they originate from google. I do not want them.

They originally appeared under server certificates I deleted these and then they keep appearing under other. If I delete them and select OK then they reappear every time I look at certificates. This has happened even after reinstalling firefox. They say they are

Did you click the View button to inspect those certificates to see their status?

Most (or all) certificates that show on the server tab aren't trusted, but disabled permanently and shouldn't be removed.

You can rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.

If that helped to solve the problem then you can remove the renamed cert8.db.old file.
Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.
Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.

If that didn't help then remove or rename secmod.db (secmod.db.old) as well.
