Hi KamT, did you get the studies related to this fix, or did they never show up on the about:studies page? If you got the studies, check whether the certificate was added. That would be on the Options/Preferences page: * Windows: "3-bar" menu button (or Tools menu) > Options * Mac: "3-bar" menu button (or Firefox menu) > Preferences * Linux: "3-bar" menu button (or Edit menu) > Preferences * Any system: type or paste '''about:preferences''' into the address bar and press Enter/Return to load it In the search box at the top of the page, type ''cert'' and Firefox should filter to the '''Certificates''' section. Then click the "View Certificates" button. Check the "Authorities" tab to see whether Mozilla is listed with the new certificate. You can compare the attached screenshot. ---- If you got no studies and no certificate, try the manual method listed in this reply and/or the ones that follow: https://support.mozilla.org/questions/1258208#answer-1218876
