Firefox 19 released, comes with a built-in PDF viewer

Firefox 19

Firefox 19 is officially released for public today and available for download over at Mozilla Firefox website. Apart from bug fixes and start-up speed improvement, Firefox 19 comes with a built-in PDF viewer.

The PDF viewer kicks in when you click on a PDF link, which will open up a new tab and show basic PDF viewing functionality, such as

  • Show/Hide document outline (with all the pages on the sidebar)
  • Going directly to specific pages
  • Zooming in and out (also a few zoom options such as fit to page, etc)
  • Presentation Mode (Full screen)
  • Print the PDF
  • Download the PDF file

There is no separate search function but you can still use CTRL-F to search for particular keywords as you normally would on a web page.

Firefox 19 PDF viewer

Though there’s a warning on top of the browser that it may not be viewed correctly, in my tests, Firefox 19 built-in PDF viewer works flawlessly.

If you are using Firefox then you may want to upgrade to Firefox 19, or alternatively, wait for Firefox 50, which shouldn’t be too long…
