Since Firefox version 52 was released March 7, 2017, installed NPAPI plugins have not been supported in Firefox, except for Adobe Flash Player. Some of the plugins that no longer load in Firefox, even though they may be installed on your computer, include Java, Microsoft Silverlight and Adobe Acrobat.
Over the past few years, Firefox has implemented various Web APIs so that websites can do the same things they’ve always done without plugins, so you will most likely not notice any change to your browsing experience.
The internet is full of websites that go beyond static pages, such as video, sound and games. While NPAPI plugins, especially Flash, have helped enable these interactive pages, they also make your browsing slower, less secure and more likely to crash.
Over the past few years, Firefox has worked hard to build replacements for these plugins, these replacements are called Web APIs. Web APIs are designed to replace the function of the NPAPI plugins without undermining your internet security, stability and performance.
Before, while these Web APIs weren’t quite ready, Firefox started to transition by making plugins load manually (click to activate).

Now, many sites have adopted Web APIs, and almost all your favorite pages can be enjoyed without using old and insecure plugins. Firefox joins other modern browsers like Google Chrome and Microsoft Edge by removing support for these NPAPI plugins.
We recommend that you update Firefox if you can.
Every update of Firefox includes important fixes and improvements, including improvements that help keep you secure on the Internet. Using an old version of any browser, including Firefox, puts your personal data and even your computer at risk.

Firefox has expanded to support features that used to require extra plugins. Plugins, on top of that, are also kept up-to-date automatically and managed through blocklisting for added security. So you can stay current with just one Firefox update.
Firefox 52 began its roll out yesterday, bringing a bunch of small iterative improvements to the fore.
Among the most significant change in the release is the decision to disable support for all NPAPI plugins bar Adobe Flash by default.
This is a good move in the round as NPAPI is a terribly outdated technology (over 20 years old, in fact). Whatever bonuses these plugins, Flash, Silverlight and Java among them, offered have been long since outweighed by the inherent security flaws manipulated to malicious ends.
Google Chrome ditched NPAPI support back in 2014 (and the version of Flash that ships pre-bundled uses the newer PPAPI tech).
But it is in Firefox 52, with Mozilla’s first step towards total removal of the technology from its browser, that is likely to impact Linux users the most.
Renable NPAPI Plugin Support in Firefox 52
If there’s a particular NPAPI plugin that you rely on there is (for now) a way to override Firefox defaults and re-enable NPAPI support.
Reader Grof has all the details.

“This is important, because some websites are still using Java plug-ins, like for example our government site for signing documents. You can’t work with government if no Java plugin is present,” he explains.
Npapi Support Edge
“But there is a way to enable Java, Silverlight etc NPAPI plugins in Firefox 52 using an about:config setting. Add new Boolean string 'plugin.load_flash_only' and set it to false. Then restart the browser.”
That’s it; assuming your NPAPI plugins are installed correctly they should work as before.
It’s a Short Term Solution
In Firefox 53, Mozilla will remove this workaround. Consider this a short-term, stop gap solution. If you think you’ll need a little longer to transition away from such plugins you should download Firefox ESR (Extended Support Release), where NPAPI plugins will continue to work for another year.
