The Electronic Frontier Foundation (EFF) has announced the release of a beta version for its HTTPS Everywhere extension for Firefox on Android.
HTTPS Everywhere is produced as a collaboration between The Tor Project and the EFF.
The extension rewrites all requests to sites from HTTP to HTTPS whenever possible - i.e. it the website supports HTTPS in the first place - and by doing so increasing users' security and privacy. Until now, it was only available for desktop versions of Firefox, Chrome and Opera.
