How do I disable "cast to Roku" in Firefox?

Posted

I've been using Firefox Beta on Android for a while now.

Recently my household purchased a Roku, a type of HTPC. While I was watching a video in Firefox Beta, I noticed a new button in the video UI, that said "Cast to <my Roku model>". You can read more about this feature here: https://support.mozilla.org/en-US/kb/use-firefox-android-send-videos-your-roku

How do I disable this functionality? I appreciate Mozilla adding convenient features, but I don't want to be in my room watching a private video, accidentally press this button (it's right next to the other controls), and have my video play on the living room TV where my roommate is sitting.

Try to set this pref to false on the about:config page.

  • browser.casting.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Does this flag only exist in FF for Android?
