Mozilla Will Start Blocking Flash Content in Firefox in August 2016

Mozilla has decided to join in on the stabbing death of Flash across the Internet as they announce that starting in August Mozilla will block non-essential Flash content within Firefox. Which content specifically will be blocked can be seen in the following blocklist published on Github. Mozilla will expand this list over time, before finally making all Flash content click-to-activate in 2017.

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%. To minimize website compatibility problems, the changes are initially limited to a short, curated list of Flash content that can be replaced with HTML. We intend to add to this list over time.

Firefox cites plugin crashes as a major push for their decision to no longer support Flash, and frankly I can’t blame them. Take a look at the following chart showcasing plugin crash rates in Firefox:
