Mozilla announced the other day that its popular Firefox web browser, which is being used in the majority of GNU/Linux distributions by default, has hit a new milestone, version 49.0, bringing various new features, such as updated Firefox Login Manager and Reader Mode or better video performance on SSSE3 systems without hardware acceleration. Mozilla Firefox 49.0 also ships with updated HTML5 video and audio technologies that let users play files at 1.25x speeds or loop them. To track font memory usage, Firefox 49.0 contains new improvements to the about:memory reports, and it looks like there’s now better font shaping thanks to the re-implementation of the Graphite2 rendering engine by default.
