Mozilla recently rolled out Firefox 19 to its stable browser channel, bringing several new features and bug fixes to the masses. The most prominent new feature is a new built-in PDF reader that is now enabled by default. Using the PDF.js javascript libraries, the reader converts PDF files into HTML5 web pages. It is nice to see Mozilla incorporating the reader in the browser by default, eliminating the need for users to use Adobe Reader or other browser plug-ins (like this one we covered previously).

 

Additionally, Mozilla has fixed several bugs and improved performance. The browser will now start-up more quickly than previous versions, and a WebGL drawing operation error has been corrected, for example. Further, Firefox 19 now recognizes more CSS features including @page and support for fixed-width text transformations. A new debugger has also been added to Firefox 19, which should help add-on developers test their code. Also in interesting news, mobile users running Firefox for Android will also be pleased to know that Mozilla has relaxed the CPU clockspeed requirement to a mere 600 MHz–allowing the mobile browser to run on even more Android devices.

The new version is available for download from the Mozilla website.
