Firefox 19 released, adds HTML5 PDF viewer

Mozilla has released Firefox 19 for Mac today. The updated web browser offers a number of bug fixes, however it's the new HTML5 PDF viewer that users will immediately notice. Firefox users will no longer be required to download Adobe's Reader PDF plugin -- something which could be buggy and slow to load. The new PDF viewer built into Firefox 19 is built using HTML5 so it's pretty snappy.

Unless they're really into web development, the average user probably won't find any of the other updates too appealing. Here's the full release notes:

  • Built-in PDF viewer.
  • Canvas elements can export their content as an image blob using canvas.toBlob().
  • Startup performance improvements (bugs 715402 and 756313).
  • Debugger now supports pausing on exceptions and hiding non-enumerable properties.
  • Remote Web Console is available for connecting to Firefox on Android or Firefox OS (experimental, set devtools.debugger.remote-enabled to true).
  • There is now a Browser Debugger available for add-on and browser developers (experimental, set devtools.chrome.enabled to true).
  • Web Console CSS links now open in the Style Editor.
  • CSS @page is now supported.
  • CSS viewport-percentage length units implemented (vh, vw, vmin and vmax).
  • CSS text-transform now supports full-width.
  • Starting Firefox with -private flag incorrectly claims you are not in Private Browsing mode (802274).

Firefox 19 is a free download.
