Firefox 52 block all NPAPI plugins, Netscape Plugins API, are a kind of old, archaic and poorly programmed web plug-ins required for many web pages to function properly. Much content, such as Java or Silverlight depend on this technology and although there are many more professional alternatives like the current standard HTML5, many pages have not yet been updated and continue to depend on these plugins.
Since those responsible for the web pages do not decide to update them to the new standards to eliminate these complements, it has finally been the developers themselves who have had to take the step. Google Chrome, for example, has already blocked all NPAPI plugins since mid-2015, dramatically improving browser security and performance. Firefox, on the other hand, has continued to support this technology by allowing users to load NPAPI content from the browser so far.
Although Mozilla already said in 2015 that its browser would no longer be compatible with NPAPI plugins, it has not been so far when it really has taken the step to do so.
As confirmed by one of the engineers of Mozilla, with the arrival of the new Firefox 52 , scheduled for next March 7, 2017 , the browser will no longer be compatible with this type of add-ons. In this way, from this version, if we try to load, for example, a web with Silverlight or use Java, we can not do it with the Firefox 52 browser.
Flash, once again, becomes an exception . Unlike Google Chrome, which has its own plugin for Flash, Firefox depends on the NPAPI plugin for this type of content and, being (unfortunately) still very relevant in web pages, it has been decided that it will continue to be maintained, at least For the time being.
Firefox 52 block all NPAPI plugins
A few years ago, all the multimedia and interactive content of web pages, such as video, audio and games, for example, relied on additional add-ons such as Java, Silverlight or Flash to be embedded in web pages and loaded into browsers. Fortunately , the new HTML5 standard is already capable of delivering everything the plug-ins offered, as well as being much safer and faster than NPAPI plugins.
It is true that these add-ons have been very important in shaping the Internet and that without them, web pages would not be as we know them. However, we are talking about abandoned software (such as Silverliglt, for example), obsolete and vulnerable, so ending it will undoubtedly benefit the Internet. The problem is that many developers refuse to update their web pages to the new HTML5 standard, and therefore, NPAPI add-ons like Flash do not end up being forgotten.
Firefox will continue to be compatible with the NPAPI plugins, although Mozilla has also confirmed that it will eventually depreciate them until the release of the next ESR 53 release, which will definitely end support for those add-ons.
In case you need to load any of these add-ons for some reason, we recommend using Internet Explorer , because, at the moment, it does not impede any type of content.
