I am getting this error on several sites, "Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL". I see this has been an issue for many years but have not been able to find an answer. I have never set any certificate exemptions. Chrome works fine with the problematic sites so I don't think there is an issue with my router. Thanks for any help, I can't wait to stop using chrome.

You can try to rename/remove the cert8.db file in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Thanks for replying. I have tried removing that and another cert... file, restarting and nothing changes.
