hello, i don't think that this would be the case in firefox - where did you read that?

Google's announcement is here: Chromium Blog: Saying Goodbye to Our Old Friend NPAPI

I'm not aware of any time line for ending "NPAPI" plugin support in Firefox for desktop systems. However, the "click-to-play" feature, which has been modified in several recent releases, might get some further revisions...

The article is misleading. As written it looks like it is being blocked, but it is the click to play feature they are talking about.

yes, firefox will put all plugins except the current version of flash on click-to-play on default - however users still have the choice to keep them always activated or on demand...
