For a number of years browser vendors have been working to provide web applications a more secure and robust way to create rich interactions. A significant part of that effort has been to reduce the dependency on the Netscape Plug-in API (NPAPI). For more information on this trend, check out our post The Death of the NPAPI.
Following Google Chrome’s discontinuation of NPAPI support in September 2015, Mozilla is scheduled to discontinue its own support with the release of Firefox 52 on March 7, 2017. You can read Mozilla’s October 2015 announcement to learn more about their reasons for making this change.
Anticipating Google’s earlier decision, in 2015 we created the Signiant App that eliminated dependency on NPAPI. Since that release many of our customers have successfully moved over to the Signiant App.
