Enable the Built-in PDF Reader in Firefox 15
Mozilla recently rolled out Firefox 15, the latest version of the browser in their new rapid-release schedule. Â With this new release there are quite a few new features, which have been outlined in the above linked post. Â One interesting feature that bears a little more attention and some explanation is the new built-in PDF reader.
Building a PDF reader right into the browser is important for a couple of reasons - one is that it speeds up the execution of these files online, but the other is security. Â Previously users have mostly plugged the Adobe PDF Reader into their browser because it's well known and it's also the first option that comes to mind for many. Â However, the Adobe app is notorious for it's security problems. Â With the new Mozilla feature we will, hopefully,Â get a more stable and secure way to view these files online.
Before we get started you will need to make sure you are running Firefox 15 (or higher if you subscribe to the beta). Â To do this you can simply click the "Help" option on the menu bar and choose "About Firefox". Â This will not only display the currently installed version, but also prompt you to update if you aren't running the newest build.
Now, in the address bar, type "about:config" and hit "Enter". Â If this is the first time you have accessed these settings then you may be surprised by a pop-up message that will warn you about making any changes. Â Don't panic, just click "I'll be careful, I promise!"
In the search bar type "pdfjs.disabled" and then right click this option. Â In the context menu choose "Toggle" to change the setting from "True" to "False". You can alternatively double-click the entry.
You have now enabled the the PDF reader in Firefox. Â Browse to a site that has a ".PDF" extension and try it out. Â We have high hopes that this will solve the previously mentioned security woes that came with Adobe and perhaps make the browsing experience a bit faster as well.Advertisement
