What is happening with the Silverlight plug-in for the Firefox browser in September 2015?
I have heard that Firefox will no longer support the Silverlight plug-in as of September 2015: does that mean all automatic updates will disable the Silverlight plug-in and it will have to be re-enabled, or does this mean that platforms depending on the Silverlight plug-in will simply cease to work in the Firefox browser?

For Win64 Firefox builds as of 41.0 only the 64-bit Flash Player is white listed to run in Win64. The Firefox 41.0 Release may be the first to have Win64.
You can still use 32-bit Firefox and all 32-bit NPAPI plugins installed on Windows system then. The 64-bit Mac OSX and Linux Firefox will still be able to use any NPAPI 64-bit Plugins.
There is no real Silverlight support for Win64 Firefox builds anyways.

Google has announced plans to discontinue support for Silverlight in the Chrome browser in September.
As far as I know, there are no changes planned for Firefox's support of Silverlight and other NPAPI plugins.

Amazon.com only offers the Silverlight plug in for watching video content on the Firefox browser. I used to be able to use the Flash player, but that has been discontinued. When I try to download Silverlight I am told by the install program that my operating system does not support the 64bit version of silverlight, even though I am running Vista64 Ultimate. They have tried to help me but have no answers that I have not already tried. What is the HTML5 player, and will Firefox support it in the future?

Hi Kapryan, as noted in your other thread, Firefox for Windows uses the 32-bit version of Silverlight because Firefox for Windows is a 32-bit application. https://support.mozilla.org/questions/1086485

Firefox for Windows already supports HTML5 video playback on YouTube and other sites (except: MP4 doesn't play on Windows XP). It's up to the site to specify whether it wants to use that capability or use a plugin. I don't know what Amazon is thinking.

Are you using 32-bit Firefox or trying to use Win64 Firefox? which cannot run on 64-bit Vista. If 32-bit Firefox you need 32-bit Plugins even though you have 64-bit Vista.
The Win64 Firefox builds from mozilla.org requires Windows 7, 8 or 10 as the Win64 Firefox builds cannot run on 64-bit WinXP, Vista or servers.
