Adobe Flash has been running out of favour from major browsers for quite some time now. HTML5 has made theWeb plugin look redundant and dated. The latest step taken in the direction of discontinuation is by Mozilla Firefox, which has decided to step away from the plugin by blocking “certain Flash content that is not essential to the user experience” from August and then keeping it off by default starting 2017.Mozilla has said in a blog post that although the browser will continue to support legacy flash content after August, starting 2017, it will require “click-to-activate approval” before a website activates Flashplugin for any content.In its note, Mozilla acknowledged the role of Flash in providing video and interactive content on Web but said that it often introduces stability, performance, and security issues for browsers and therefore it becomes a necessity to introduce these changes.It added that these changes will result in enhanced security, improved battery life, faster page load, and better browser responsiveness for the users. It even claimed that blocking certain Flash content will result in reductions in hangs and crashes by up to 10 percent.The browser company also advised websites that currently use Flash or Silverlight for video or games to plan on adopting HTML technologies as soon as possible. Mozilla has said that it will, however, continue to work with Adobe to improve the Flash experience, whenever the plugin will be enabled on its browser.This is not the first step Mozilla has taken towards reducing usage of Flash in its browser. Back in July last year, following a major vulnerability being found in Flash, blocked all versions of the Web plugin by default.
