HowTo: Firefox Disable Default PDF Viewer / Plugin

in Categories last updated March 7, 2013

I recently updated my Mozilla Firefox. Firefox now includes a built-in PDF viewer that allows me to see PDF files found on the web without a plugin. The built-in PDF viewer is enabled by default. However, I found that this pdf viewer is not working properly with various web-sites, and it works slowly. How do disable the built-in PDF viewer so that I can use the Adobe PDF viewer or other PDF viewer that is shipped with my operating systems?

I‘ve upgraded to Firefox v13. However, I don’t like the new tab page. I’m concerned about my privacy. How do disable or hide new tab page while using Firefox browser version 13? How do you get rid of the “new tab” page that shows recently visited pages?
