Content for Adobe’s Flash Player will be blocked by default from Firefox 55. From,that version it will also only be possible to load Flash files over HTTP and HTTPS, local Flash files can no longer be accessed from the browser. On websites that still require the browser plugin, Flash content will be ‘click-to-play’.
Plugins that still use the old Netscape Plugin API (NPAPI) are responsible for performance issues, crashed and vulnerabilities, according to Mozilla. The browser developer has therefore stopped supporting NPAPI plugins like Silverlight, Java and Acrobat. For Adobe’s Flash Player the company made an exception because it’s still so frequently used on the internet.
Firefox 55 should be released on the 8th of August this year. Users that want to experience how Firefox 55 will deal with Flash can already download a Firefox Nightly, an early test version of the browser.
