65.0

Firefox for Android Release

January 29, 2019

Version 65.0, first offered to Release channel users on January 29, 2019

We'd like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!

New

  • Improved performance: Scrolling is faster and more responsive.

  • Improved performance and web compatibility, with support for the WebP image format: WebP brings the same image quality as existing formats at smaller file sizes, which saves bandwidth and speeds up page load.

Fixed

  • Restored Chromecast controls to the location bar.

  • Various security fixes.

Changed

  • Enhanced security for macOS, Linux, and Android users via stronger stack smashing protection which is now enabled by default for all platforms. "Stack smashing" is a common security attack in which malicious actors corrupt or take control of a vulnerable program.
