Easier to be aware on a 64-BIT browser since many if not most plug-ins have no 64-BIT declination (yet) and that is, as far as I’m concerned, the last of my worries. I’m running Firefox 42 64-BIT and, if I use 64 (!) add-ons, I have not one plug-in installed. We are dealing with evidence, not with gadgets seemingly dressed up with a pseudo-improvement attitude in order to legitimate what is or can be an intrusion and/or a degradation of users’ liberty : NPAPI must no longer be supported, even as a “tolerance” interval to allow sites to move their a*s. I’m not a radical but there are times where a choice is incompatible with consensus. I believe browser developers should impose the natural course of technological evolution to websites and their administrators. I dislike the dilemma between audience and progress imposed by reluctant sites to adopt latest technology. I don’t use Silverlight, no more than Adobe’s Flash, I am of those who believe that html5 (browser capability to manage audio and video) is already a reality and fulfills tomorrow’s browser aims. That does not mean that they cannot protect their users by default, for instance by setting plugin contents to "click to play" instead of running them right away.
I think that browser developers should leave it up to the user to install and use plugins, provided that they don't cause instabilities or have known security vulnerabilities. Pale Moon for instance won't follow Mozilla, Google and Microsoft according to a post on the official forum.
First, they can block updates of the browser to retain plugin functionality, or keep an older copy around for that purpose, or they may use a browser that won't discontinue support.
Neither Google with its Chrome browser nor Microsoft's new browser Edge support Silverlight anymore.
It is interesting to note that Firefox is one of the few mainstream browsers left that supports Silverlight. Lastly, for what it's worth, I have never been able to get the "about:config" suggestion to work.This ends support for Silverlight and other browser plugins that depend on NPAPI in all versions of the Firefox web browser. My next project is to install Windows Firefox ESR via Wine (v.2.3-staging since it "emulates" Windows 7), then install Silverlight as a plugin
Mac All major operating systems as well as most major browsers such as Firefox, Google Chrome, Safari, and indeed Internet Explorer accept Silverlight. Can't find anything specific on google but there seem to be some problems with FireFox 3.6. The button doesn't appear in FireFox though. I just started making a Silverlight 4 application and added a button to it. Is Firefox keep displaying that it had a problem and crashed, forcing you to restart This annoying issue can be fixed. It doesn't work now, as that config is removed. Interactive media experiences, rich business applications, and immersive mobile apps are now possible with Microsoft Silverlight, an interactive browser plug-in.

I see the comment regarding Midori & Webkit, and in my simple way of understanding, it looks like Midori picks up whatever is installed systemwide. In regard to Midori, I am able to run both Flash & Silverlight in the Windows version (not Linux) It asks to "Activate," but that can be changed in "Add-ons" to "Always Activate" įor what it's worth, I was able to get both Flash & Silverlight working in Firefox ESR on Windows (not Linux) I installed ESR into a separate directory (obvious) and created a "clean" profile specific to ESR Once I created the profile, I was able to install the Silverlight plugin. The Win64 Firefox still only allows the 64-bit Flash Player and Silverlight Plugins.
You should be able to use the Firefox 52.0 ESR to use Silverlight and other Plugins as if you were using Firefox 51.0 and older whether on Windows, Mac OSX or Linux. James wrote:The Firefox 52.0 and later Releases on Windows, Mac OSX and Linux only allows the Flash Player Plugin to run.
