My UserChrome.css is edited to block the message when using fullscreen. The new update has a new fullscreen message, and ignores the code written in the UserChrome.css.

I am currently using this code, (its no longer working):


@namespace xul url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

  1. full-screen-warning-container{display:none!important}

As you may know, the purpose of this is to alert you that the site has invoked full screen in case you were not expecting that to happen, since evil sites may use full screen to emulate a site you trust.

This full screen message changed in Firefox 43, and there are some new settings which control how soon and how long the message is displayed. Probably of most interest to you if you never want to see the warning is the following:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste FULL- and pause while the list is filtered

(3) Double-click the full-screen-api.warning.timeout preference and enter the display time. For example:

  • 3000 => displays for 3 seconds (default)
  • 500 => displays for 1/2 second
  • 0 => no display at all

Thank you, that worked.

I understand the risk of something trying to replicate a website or keylogging, I am willing to take the risk when dealing with this annoying feature.

I really wish mozilla would allow a "trusted" site for us to select this option.

It used to work that way a few versions ago, but people objected to having to approve each site they visited to use full screen.
