Firefox has become the latest browser company to turn off support for the ageing Adobe Flash plug-in.
The Firefox browser will turn off "not essential" Flash content by default starting in August, but sites that require the plug-in for heritage functionality will be excepted.
"These and future changes will bring Firefox users enhanced security, improved battery life, faster page load and better browser responsiveness," said Mozilla in a blog post.
Firefox, like rivals Chromium and Microsoft Edge, has reduced its reliance on Flash as the industry moves towards the much safer HTML5 rendering method.
But even Adobe has confirmed that its time has come, although the firm won't abandon Flash support until necessary.
The move away from Flash really began with the rise of Android, as the Chrome browser removed support for Flash in 2011.
Chrome also now blocks adverts by default if they contain Flash content, and Google's ad providers no longer accept Flash-based advertising.
Meanwhile, Firefox is beginning the process with a curated blacklist of sites that can work without the Flash plug-in, expanding to become a 'click to run' model for all content during next year.
Mozilla has already confirmed that, like Google, it will abandon support for all NPAPI (Netscape) plug-ins other than Flash from March 2017. This effectively kills Silverlight and Java too, although an extended support release will be available until 2018 for those needing a little longer.
The need to kill off Adobe Flash has long been recognised. The player required 78 patches in December 2015 alone to cover security bugs in the code.
The blog post from Mozilla also demonstrated that the expected crash rate of Firefox has reduced significantly since key sites such as YouTube switched to HTML5.
