Why can't Firefox open websites but Internet Explorer can?

Posted

I use Windows 10 Version 1803(OS Build 17134.228). I use Firefox Quantum 62.0(64-bit). After the most recent update to Firefox, Firefox can no longer open 75% of the websites I routinely surf. All of the offending websites supposedly have certificates with invalid signatures. Oddly enough, those same websites are no problem to Internet Explorer, Google Chrome, Opera or Microsoft Edge. What are you guys trying to do, Shoot Yourselves in the Foot Again? Get this crap fixed.

What is the exact error messages? There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own. 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 [https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors?redirectlocale=en-US&redirectslug=Error+loading+web+sites Websites don't load - troubleshoot and fix error messages] http://kb.mozillazine.org/Error_loading_websites
