Software giant Mozilla is trying to add PDF rendering to its Firefox web browser using HTML5 and JavaScript, Mozilla researcher Andreas Gal announced.

PDF rendering to Firefox using HTML5 and JavaScript will allow users to get rid of the need to run Adobe's own plug-in.

Gal revealed that the company had been working on the project for months, and the PDF reader may be included in the search engine within a period of three months.

If Mozilla implements the plan successfully, Firefox would become the second major browser, after Chrome, to offer in-browser PDF rendering.

But, there will be disparity in the working of in-browser PDF rendering on the two browsers. Google’s Chrome depends on an API to create its own native-code plug-in, while Mozilla will make use of HTML5 and JavaScript to display Adobe's document format.

Touting HTML5’s security, Gal said, “An HTML5-based implementation is completely immune to this class of problems.”

To begin with, Mozilla will offer the in-browser PDF viewer through a Firefox extension; however, the ultimate goal is to offer the viewer inside the browser.
