There is a technical difference between the PDF rendering components in IE and Firefox. IE uses an ActiveX control while Firefox uses a "Netscape-style" plugin. Do you know whether your JAWS software can work with both?

As a workaround, you can launch PDFs from Firefox into Adobe Reader. To do that, try changing your application preference here:

orange Firefox button or classic Tools menu > Options > Applications

In the search box, type pdf and pause while the list is filtered. Change the drop-down control on the right side from "Use Adobe Acrobat (in Firefox)" to "Always Ask".

(If your Firefox is current set to use Foxit or another non-Adobe reader, you could try changing it to "Use Adobe Acrobat (in Firefox)" and see whether that actually works.)

I have changed my option from "Use Adobe Acrobat (in Firefox)" to "Always Ask". But still JAWS not reads the PDF document content. but when clicking inside the document it will reads the content. Can you please let me know what I can do for that??

Hi sanakkian, when you mention clicking inside the document, are you clicking the plugin in a web page, or clicking in Adobe Reader?

Do you recall whether JAWS could read PDFs in earlier versions of Firefox, and if so, how long ago it was?

Try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
