How To Open PDF Files In Firefox

There are a number of reasons why computer users prefer Google Chrome over Mozilla Firefox. One of the reasons why many Firefox users switched to Chrome is the lack of support for PDF files. Unlike Google Chrome, Firefox doesn’t allow you view PDF files within the browser without the help of third-party extensions.

Despite the fact that it’s not as feature rich as Google Chrome, Firefox is still one of the best and widely used web browsers. Mozilla has been working hard to speed up the browser and introduce new features.

We have a good news for Mozilla Firefox lovers. Firefox users can now open and read PDF files within the browser without having to install third-party extensions. Mozilla has introduced support for PDF files in the recently released Firefox v15.0 but for some reason the feature is disabled by default in the current version. Users need to enable this feature to able to open PDF files.
