Firefox for Android Release

January 23, 2018

Version 58.0, first offered to Release channel users on January 23, 2018

With this release, we’re building on the great foundation provided by our all-new Firefox Quantum browser. We're optimizing the performance gains we released in 57 by improving the way we render graphics and cache JavaScript. We also made functional and privacy improvements to Firefox Screenshots. On Firefox for Android, we’ve added support for Progressive Web Apps (PWAs) so you can add websites to your home screen and use them like native apps.

Thank you to all of the new Mozillians who contributed to this release of Firefox!
