Hello, the Secure Connection Failed started up after one of your recent updates. It is affecting News Max and my banks internet banking software. Both sites work fine in MS Edge. The fix I read on your site said to try this: "In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise! to continue to the about:config page. copy the next security.ssl.enable_ocsp_stapling and paste it in the search field double-click on it to make it false close the page, exit firefox and restart it. " Doesn't work for me. What else can I try? Take care, Doug
