it is probably better if you explain what the problem is rather than ask about policy, but note that there are generally good alternatives to using Plugins, and that FlashPlayer support is being continued for longer than others because it is unfortunately still used by some websites.

For further information on policy see the blogs

Trying to use old versions of Firefox is risky and best avoided entirely, or used in only strictly limited situations. Please take note of

• Install an older version of Firefox

The then Firefox 52.0 ESR may be supporting other Plugins still besides Flash Player.

Hi siddu, the schedule has changed, so no need to panic until March 2017.

In Firefox versions where NPAPI based plugins currently work they will continue working, but using older Firefox versions that no longer receive updates is not recommended. In such a case there are portable Firefox versions for Windows that you can consider. It is also likely that developers of NPAPI based plugins will stop supporting these plugins with updates. It is likely that Flash may still be supported for a longer time.

Note for for 64 bit Firefox versions for Windows only the Shockwave Flash plugin and Silverlight plugins are enabled, so NPAPI plugin support for the 64 bit Windows platform platform is already minimal.

Plugin suppport has been dropped in Firefox 52 other than Flash. The upcoming Firefox 52 ESR version will keep the plug-in support enabled until May 2018.
