Firefox: AD and other PDF File Viewing

If you use Firefox as your browser, you may experience some issues viewing ADs and other PDF files.

Firefox, by default, automatically downloads any PDF files it encounters, and does not display them on the screen.

The good news is that there is a solution!

Depending on the version of your Firefox, you can either change the settings so it will display PDFs on screen, or you can activate an Add-on.Β  Either way should help with viewing ADs and other PDF files.

Here’s one way to change the settings:

Open Firefox.Β  In the menu bar, click Firefox, click Preferences.Β  This will open the Settings page.

In the Search box, type “pdf“.

It will display a list that you may have to scroll through.

Locate Portable Document Format (PDF), and click the drop down on the right side.

Select Open in Firefox.

You’re all set.Β  It should now display all PDFs on-screen.
