Firefox will stop supporting web plugins (except for Flash) by the end of 2016
Horrible browser plugins used to offer extended multimedia features for website, often at the cost of a much worse overall experience -- thankfully, they're going the way of the dodo. Chrome recently banished plugins like Java and Silverlight (and made auto-playing Flash ads disabled by default), and now Firefox is doing the same. Mozilla just announced in a blog post that nearly all old-school plugins will not be supported in Firefox by the end of 2016. That's a long ways away, but it's still good news.
Naturally, the impossible-to-kill Adobe Flash platform is exempted from this doom, but everything else will be completely disabled. Mozilla also noted that new platforms, like the 64-bit Firefox for Windows, will launch without plugin support since they don't have to support a legacy base of users. Let's take a moment of thanks for standards like HTML5 making the web a better place to browse and start counting down the days until Flash can join Java in the internet's trash pile.
