Request Firefox to extend support for Silverlight as it would affect more than 20000 users of our product and we would be forced to move to a different browser
The preferred browser for our product is Firefox and silverlight extensively used by use. If Firefox stops supporting Silverlight than it would affect more than 20000 users of our company and we would be forced to more to a different browser. Hence request Firefox to extend their support for Silverlight so that we can continue using Firefox as our preferred browser.
I doubt that policy is going to change. See for instance
- NPAPI Plugins in Firefox
.... Mozilla intends to remove support for most NPAPI plugins in Firefox by the end of 2016. Firefox began this process several years ago with manual plugin activation, allowing users to activate plugins only when they were necessary. This decision mirrors actions by other modern browsers, such as Google Chrome and Microsoft Edge, which have already removed support for legacy plugins. Moreover, since new Firefox platforms do not have to support an existing ecosystem of users and plugins, new platforms such as 64-bit Firefox for Windows will launch without plugin support. ....
You may have difficulty finding an alternative browser to use.
We do not have any Developers here but if you want to try posting a plea where Developers will see it please try the Mozilla Mailing lists & Fora
Yes, by sticking with this proprietary technology you will be forcing your users to run your application in Internet Explorer 11, as that is the only browser Microsoft plans to support after Firefox 52.x or 12/31/2016, according to Silverlight 5 System Requirements.
That said, your users can stretch out their use of Silverlight in Firefox by switching to the Extended Support Release version of Firefox 52 next February instead of moving to Firefox 53. The 52esr version should receive security updates through about the end of next Summer (I don't know the precise calendar).
Correction to my earlier reply:
Firefox 52 will still run the Flash plugin, but not the Silverlight plugin.
Users that need Silverlight will have to switch to the Extended Support Release version of Firefox 52 instead of the regular release. Both are scheduled to become available in early March 2017.
