I had to go to my phone for an answer because I couldn’t load Google from my desktop. I wouldn’t be surprised if Mozilla’s market share dropped from 10% to below 5% overnight because of this catastrophe. Now You: Did you run into Secure Connection Failed issues with Firefox 61? If you don't run Avast try to find an option in the settings to turn of HTTPS scanning to resolve the issue. Other security solutions may use similar components that interfere with HTTPS traffic.

When you try to load sites that failed to load in Firefox 61 previously you will notice that the sites load just fine. Select ok to save the change and ok on the next page to return to the main interface. Locate 'Enable HTTPS Scanning' and uncheck the box. Select the customize link displayed for the Web Shield component. Switch to the Components section in the sidebar. Select Menu > Settings to display all program preferences. If you run Avast, you can disable the HTTPS scanning part of the security software's Web Shield to resolve the issue without dropping the maximum TLS version in Firefox from 4 to 3.ĭouble-click on the Avast software icon in the System Tray area to display the main interface of the application. Chance is that you have Avast, AVG, or other security software installed on the device that interferes with HTTPS traffic.
