More than half of Mozilla users are now using HTTPs.
Mozilla developer Josh Aas says the browser baron's telemetry reveals more than 50 percent of page requests were made via HTTPS, an effort helped along by the Let's Encrypt initiative which hands out free HTTPS certificates.
Aas says it was the first time the benchmark had been broken.
It comes as the Let's Encrypt initiative had handed out more than one million free HTTPS certificates in the first week of October.
All told the lauded initiative has given away some six million certificates to help rub out man-in-the-middle and other interception attacks.
