I have a webapp that requires the frequent and repeated use of the Pointer Lock API. Using this web-API will display a browser-specific popup-message to the user, something like:

site is controlling the mouse. Press ESC to exit.

The message is only displayed once in Chrome and Edge, initially, which I can cope with. However, it is displayed every single time in Firefox, which is annoying from a usability perspective.

Where can I disable this message in Firefox? (53.0.2) I already looked in page permissions, but there is no setting for this.

On the about:config page (accessible by writing "about:config" into the URL bar), set the following:

pointer-lock-api.warning.timeout

to 0.

This will, in essence, hide the warning immediately, without giving it time to show up.
