[Affected versions]: - Firefox Beta 64 and above [Affected Platforms]: - All Windows - All Mac - All Linux [Prerequisites]: - Have "browser.security.newcerterrorpage.enabled" pref set to "true" in "about:config" page. [Steps to reproduce]: 1. Open the browser with the profile from prerequisites. 2. Navigate to: "https://untrusted-root.badssl.com/" and click the "Go Back" button. 3. Go to "about:telemetry"-> Histograms section. 4. Type the following string on the search box from the top right side of the page: "WARNING_BAD_CERT_TOP_GET_ME_OUT_OF_HERE = 73". 5. Observe if the "WARNING_BAD_CERT_TOP_GET_ME_OUT_OF_HERE = 73" is displayed. [Expected result]: - The "WARNING_BAD_CERT_TOP_GET_ME_OUT_OF_HERE = 73" histogram is displayed. [Actual result]: - The "WARNING_BAD_CERT_TOP_GET_ME_OUT_OF_HERE = 73" histogram is not displayed. [Notes]: - This issue is reproducible with almost all other "Histograms" described in the Telemetry doc. (link: http://tiny.cc/xyxm1y) except the "SSL_CERT_VERIFICATION_ERRORS" histogram. - Please see the attachment for the video.

Hi Remus, I tested on my end and I'm seeing the SSL_CERT_VERIFICATION_ERRORS being populated as expected in release 64 FF (mac), but in the raw json (but not the "about:telemetry#histograms-tab" page). Can you try the following: 1: reproduce steps 1-3 above 2: refresh about:telemetry page 3: click on 'raw json' (left panel) 4: click on 'raw data' in the new tab that opens (top of page) 5: check if "SSL_CERT_VERIFICATION_ERRORS" histogram exists in the raw json and has some value - Su

Hi Su-Young Hong, Thank you for following up on this. Yes, the "SSL_CERT_VERIFICATION_ERRORS" histogram is correctly displayed in the "about:telemetry->Raw Json->Raw Data" section, but our concern is regarding the other histograms mentioned in the "Cert Errors Telemetry" doc (link: https://goo.gl/bMnPxc) as follows: - WARNING_BAD_CERT_TOP = 68; - WARNING_BAD_CERT_TOP = 69; - WARNING_BAD_CERT_TOP_CLICK_ADD_EXCEPTION = 70; - WARNING_BAD_CERT_TOP_GET_ME_OUT_OF_HERE = 73; - WARNING_BAD_CERT_TOP_UNDERSTAND_RISKS = 74; - WARNING_BAD_CERT_TOP_CONFIRM_ADD_EXCEPTION_FLAG_UNTRUSTED = 85; - WARNING_BAD_CERT_TOP_CONFIRM_ADD_EXCEPTION_FLAG_DOMAIN = 86; - WARNING_BAD_CERT_TOP_CONFIRM_ADD_EXCEPTION_FLAG_TIME = 88; Can you please give us more information on the above histograms?

hey, like we discussed on Vidyo earlier, I think the probes we need validated are the histogram: SSL_CERT_VERIFICATION_ERRORS and the events of https://searchfox.org/mozilla-central/rev/fcfb479e6ff63aea017d063faa17877ff750b4e5/toolkit/components/telemetry/Events.yaml#555

As per comment 3 I will close this issue as invalid.
