Google Translate ------------------------- The connection is not secure hello, I am very tired of hours spent not finding the solution; I am obliged to use chrome to question you; Why do you stick to "The connection is not secure" for all URLs? I have 32-bit firefox V58.0.2 because the 60 was not better, I downloaded the 58. and I kaspersky 2017 18.0.0.405 I am at the point of removing all the controls by your fault. And I still have "The connection is not secure", including by your fault. And I still have "The connection is not secure", including for google.fr (the owners of www.google.fr have misconfigured their website, do you dare to write) There is no answer null part of this problem. Answer me. There, it's really too tiring. This gives the impression that you are doing everything to go elsewhere. Does Mozilla want to disappear? Ok there are other browser. Too many controls, too many barriers, no easy explanation of access. ___________________________________________________________________________________________ HI, well instead of spending hours you could have asked sooner so you would not get frustrated as it seems you are. We are here to help. 1 Issue is uninstall reinstall and bouncing around from version to version. It has made working with your install impossible. But that is ok as the problem is with your Kaspersky : There is security software like Avast/AVG, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate. *https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can *https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites *https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message *https://support.mozilla.org/en-US/kb/connection-untrusted-error-message *http://kb.mozillazine.org/Error_loading_websites *https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER If you are running any of the above software please check their community forum for a work around.
