Firefox will soon turn Flash off by default

From 2017, Firefox will require click-to-activate approval from users before a website activates the Flash plugin for content.

Mozilla said the Flash plugin introduced stability, performance, and security issues for browsers.

“Mozilla and the Web as a whole have been taking steps to reduce the need for Flash content in everyday browsing,” it said.

Starting in August, Firefox will block certain Flash content that is not essential to the user experience, while continuing to support legacy Flash content.

“These and future changes will bring Firefox users enhanced security, improved battery life, faster page load, and better browser responsiveness.”

As websites have switched from Flash to other web technologies, the plugin crash rate in Firefox has dropped significantly.

Firefox will continue this trend by blocking specific Flash content invisible to users. This is expected to reduce Flash crashes and hangs by up to 10%.

“We continue to work closely with Adobe to deliver the best possible Flash experience for our users. Our engineering partnership has led to improvements in high-DPI support on Windows, enhanced sandboxing, and an accelerated Flash rendering pipeline that improves performance and stability.”
