Mozilla auto-play Blocking Feature

Share:
Mozilla, the creator of open source browser Firefox, is adding a new "auto-play blocking" feature to the search engine for the desktop and Android users, which is to block audible audio and video playback by default. This feature will come in the form of a part of "Firefox 66", which is scheduled for a general release on March 19.

"Any playback that the user interacts with a page via mouse click, printable key press, or touch event, is considered autoplay and will be blocked if it is potentially audible," Chris Pearce, Engineer, Mozilla wrote a blog-post on Monday.

However, Firefox will allow users to opt-in to "autoplay sound" permission for "permissions" from the default setting of "block" for some websites, where users prefer audio and video audio autoplay.

"If the user has already given permission for camera or microphone, then we are allowing sites to autoplay audible so that the sites which have explicit user permission continue to work even today."

Google, Microsoft, and Apple have also added provisions to limit and mute auto-play media on Chrome, Edge and Safari browsers, respectively. Last year, Mozilla announced that Firefox will no longer support auto-playing audio on the browser.

"At this time, we are also working to block autoplay for web audio content but have not yet finalized our implementation, but in 2019 it is expected to ship this facility for some time," Pearce said.
