Here's how you can turn off the "media keys" integration: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. ''More info on about:config:'' [[Configuration Editor for Firefox]]. (2) In the search box in the page, type or paste '''mediakey''' and pause while the list is filtered (3) Double-click the '''media.hardwaremediakeys.enabled''' preference to switch the value from true to false That might not work fully until you do a regular quit/restart of Firefox. Does that work on yours? ''We probably should add something about that to the new article:'' [[Control audio or video playback with your keyboard]].
