How do I recover accidentally deleted Certificate Authority?

more options

Hi,

Running Firefox 5 on Ubuntu 10.10 and while troubleshooting some other issues, I believe I have deleted a Certificate Authority accidentally. Because of this I cannot securely access Facebook or any https Google sites. I can, however, access Bank of America and other https sites no problem.

Also, I can access these sites in Chrome without issue (but I prefer Firefox).

I'm looking for a way to recreate or repopulate the CAs. I tried uninstalling/reinstalling Firefox but that didn't seem to work. I'm at the point where I feel like I'll have to reinstall the OS, but I don't want to get to that point if at all possible.

Any ideas much appreciated.

Regards, Joe

Which error do you get and who is the issuer of the certificates that do not work?

You can only remove trust bits from build-in root certificates.

Try to Rename or remove secmod.db (secmod.db.old) in the Firefox Profile Folder.

You may have to rename cert8.db (cert8.db.old) as well.
Firefox will create new files.

Thanks for your helpful information! I think you just solved a similar problem I've been having for quite awhile.

Thank you so much, cor-el! Your steps worked like a charm. I renamed secmod.db to secmod-old.db, closed Firefox, and renamed cert8.db to cert8-old.db. Now when I opened up Firefox, Google Accounts and our JIRA helpdesk site opened up just fine.

A story should be told on how you managed to figure this out.
