Hi, I Installed Silverlight 3 toolkit, silverlight 3 sdk, silverlight tools for visual studio and silverlight regular installation. Open Mozilla Firefox and type about:config in the addressbar and press Enter.

We’ll need to use Firefox advanced configuration tool “ about:config” to re-enable support for NPAPI plugins as shown in following steps:ġ. If you also want to bring back support for all NPAPI plugins in Mozilla Firefox 52 or later versions, this tutorial will help you. The good news is that if some users want to enable support for all NPAPI plugins back in Firefox browser, Mozilla has provided a preference to turn on the support in the meantime. Mozilla decided to disable supports for all NPAPI plugins except Adobe Flash as according to the company, these plugins are the main reason behind browser crashes and other performance and security related issues. Only support for Adobe Flash Player plugin is enabled as its still widely used by websites. Microsoft recently revamped its Silverlight blog and is looking for feedback on it.In the recently released Mozilla Firefox 52 version, Mozilla has disabled support for NPAPI (Netscape Plugin Application Programming Interface) plugins such as Microsoft Silverlight, Java, Unity, Acrobat, Shockwave, DivX, etc. That’s a huge partnership for the platform, and one that isn’t likely to go away considering that Netflix CEO Reed Hastings is on Microsoft’s board of directors. I have Silverlight on my computer simply to be able to stream Netflix movies. I fall into that latter category for that very reason. But it’s still going to be about big time partnerships in getting people people to use it instead of, or at least along with Flash. Microsoft estimates that some 300,000 developers and designers are working on the Silverlight platform. Since that time however, Microsoft has released the beta version of Silverlight 3 and even won an Emmy for the Olympics coverage last summer. The stated reason was the Flash performs better, though specifics weren’t given. But back in November, the league announced it would drop Silverlight in favor of Flash.

One of those big partnerships for Silverlight was Major League Baseball’s MLB.com live-streaming service.

And Microsoft is going to need those kind of deals if it’s going to be able to compete with its aforementioned real competitor: Flash, which has something ridiculous like a 99% adoption rate on U.S. After installing Windows 10, Silverlight did not work on any of the devices (tried with Firefox, Edge and Chrome). That was undoubtedly thanks largely to a few huge events that used the Silverlight platform to stream on the web recently: notably, March Madness and President Obama’s Inauguration.
#SILVERLIGHT NOT WORKING IN FIREFOX INSTALL#
What’s impressive in Silverlight’s big install number is that it’s just for version 2, which was only released about 6 months ago. But it’s a bit odd for Microsoft to call all those other browsers out since Silverlight not only works on all of them, but to some extent needs them, if it’s to survive. Of course, that also not-so-subtly speaks to Microsoft’s own web browser, Internet Explorer, being by far the biggest in the world - despite falling market share. Instead, the company (or at least their PR firm) is noting that with 300 million installs of Silverlight 2, the platform is installed on more machines around the world than the web browsers Firefox, Safari and Chrome - combined. But that’s not who they’re calling out in some data they sent our way today. Microsoft’s Silverlight product is most directly a competitor of Adobe Flash.
