Google Chrome

PDF viewing has been a task with this browser. The reason being, Chrome and Acrobat no longer being compatible. The Acrobat/Reader plug-in for Google Chrome is based on the Netscape Plug-In API (NPAPI) technology. Google announced that in April 2015 NPAPI plug-in support would be disabled by default in the Google Chrome web browser, with an override capability for advanced users. In September 2015, NPAPI support in the Google Chrome web browser was removed entirely.

Hence, while it is not possible to view PDFs in Chrome browser directly, they can be viewed in external applications like Adobe Reader as the browser arranges for a smooth download option. There are few steps for setting the plugins in Chrome browser to view PDFs in external application.
