I get this message erroneously: >Your connection is not secure >The owner of www.youtube.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website. >This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate. >www.youtube.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER (The error code is clickable, but brings up the text of the cert, not something useful. ) The message says things that **aren't true**. I installed Kaspersky and it's causing this. We have a useful page for helping folks understand and address this problem, at https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER , but we're not directing folks to it. It's NOT TRUE that "The owner of www.youtube.com has configured their website improperly." Looking in comm-central, it looks like the error message is in 3 places, currently : https://dxr.mozilla.org/comm-central/search?q=The+owner+of+has+configured+their+website+improperly.&redirect=false ; so I'm not sure which component to file this under; making a guess at an appropriate initial choice. I'm not sure if that troubleshooting page covers all reasons for seeing the "The owner of <span class='hostname'/> has configured their website improperly. To protect your information from being stolen, &brandShortName; has not connected to this website.">" I propose changing it to something like It seems that the owner of <span class='hostname'/> has configured their website improperly. To protect your information from being stolen, &brandShortName; has not connected to this website. To troubleshoot this error, [see this support article]."> A smaller but perhaps also appropriate change would be to have the SEC_ERROR_UNKNOWN_ISSUER text link to the support article instead of do what it currently does.
Moving to an appropriate component so it can be triaged. I think there are existing bugs on this, but from a cursory search I couldn't find anything.
Component: Security: Review Requests → Security: PSM
Product: Firefox → Core
All text changes are Firefox security now and not PSM. There's bug 1442203 to track progress of improving error pages. Note that HSTS trumps any other error like unknown issuer because Firefox knows that there's a good cert for that page. I don't think this should change. That said with the new man-in-the-middle detection we might want to give that priority over HSTS.
Component: Security: PSM → Security
Component: Security → Security
Product: Core → Firefox
We have sufficient indication from Telemetry that MOZILLA_PKIX_ERROR_MITM_DETECTED is catching quite a bunch of sites and would like to start warning users when they hit an MitM induced error. https://mzl.la/2NzmHrI
Priority: -- → P2
Summary: Error message should be more useful when AV is interfering with SSL connections. → Add a new error page for MOZILLA_PKIX_ERROR_MITM_DETECTED
