Mozilla's Firefox to turn off Adobe Flash by default in 2017 - CNET

Firefox parent Mozilla is taking its battle against Adobe Flash a few steps further.

In 2017, Firefox will require "click-to-activate approval" from you before you can trigger Flash-enabled videos and other Flash content on a website, Mozilla engineering manager Benjamin Smedberg said Wednesday in a blog post. This means the Flash content will remain dormant unless you actively click on a link or icon that says: "Activate Adobe Flash."

You can currently do the same thing yourself in Firefox by manually setting Flash to "Ask to activate." But next year's move will be dramatic due to the new default status for all Firefox users.

Adobe Flash has long been a necessary feature that enables web developers to offer games, video and streaming media via web browsers. But the Flash plug-in, which gets installed in the browser, has been blasted for its constant security holes and performance problems. The industry has been gravitating toward HTML5 as a replacement for Flash, though the move has been a slow one.

Firefox has advised web developers who use Flash as well as Microsoft Silverlight for video to make the switch to HTML5 as quickly as possible. Smedberg said that Firefox supports encrypted video playback using Adobe Primetime and Google Widevine as alteatives to plug-in based video formats such as Flash.
