A strange bug has been affecting a subset of Chrome users since Monday: Embedded videos have started to automatically play as soon as a user opens the page that contains the video. However, this only happens if users also have the Google Cast extension installed, which is being used to send content directly from a Chrome browser to Google’s Chromecast streaming stick.
Google (S GOOG) engineers have confirmed the bug, and said they’re working on deploying a fix:
“The YouTube team confirmed that there was a bad push yesterday which caused this issue to be triggered. There is a fix being qualified and that is scheduled to be pushed today that will correct this issue.”
Want to stop those videos from playing right now? Then simply check your Chrome extensions, disable Google Cast for the time being, and restart your Chrome browser.
