According to Josh Aas, head of the Let’s Encrypt initiative which has been working to help smaller websites switch to encrypting their web traffic, a majority of Mozilla users were served encrypted page loads for the first time on October 13, 2016. This means their web browsing data was secured from snoopers and hackers while in transit.
Firefox collects telemetry data with the user’s consent, and if the user turns off data sharing, Mozilla deletes the data that has been collected on the server. Moreover, the telemetry feature is also not default switched on for most Firefox users but it is only for users of pre-release Firefox builds.
Mozilla, the main proponent of Let’s Encrypt CA, reported that 40% of the pages visited last December were encrypted. Let’s Encrypt aims to accelerate the Web from HTTP to HTTPS, Josh Aas said the past week Let’s Encrypt CA had added more than 1 million active certificate.
