I watch videos on YouTube, Netflix, etc. Whenever I enter full-screen mode, I get the annoying "You've entered full screen mode. Press 'esc' to exit full screen mode".

Since I'm constantly switching between programs, I see this message a lot and am severely annoyed by it. Is there a way to disable these notifications?

    I feel unconfortable, to say the least, applying a random patch to Flash.

For Firefox there are a couple of other solutions for this problem, but for Chrome I have not been able to find any.

Note: The warning is there for security reasons, because sites can otherwise - via JavaScript - automatically fullscreen themselves, and for instance disguise themselves as your desktop, while intercepting user input.
This is particularly an issue as these solutions also disable the first, related popup that asks you whether you want to allow or deny the website to put you in fullscreen, not just the notification shown after allowing a site to go into fullscreen.

Firefox

1: Via about:config

  1. Type in about:config into the navigation bar and press enter.
  2. Search for the value full-screen-api.approval-required and set it to false.

2: Via a plugin

Install the Firefox plugin Disable HTML Fullscreen Alert.

    This doesn't seem to work on Google Chrome. Would you happen to have instructions for Chrome as well?

  • You're right, it's not a general solution, though I expect looking into browser specific solutions is in general a good idea. I have found some suggestions for Chrome, like kiosk mode and white- isting all websites to go into fullscreen, but the first seemed to make no difference, and the second will only disable the popup asking for approval, not the notifications afterwards.
