Bug 1587521 - Enable FullScreen in FxR for Desktop This change enables Fullscreen functionality in the UI for Firefox Reality for Desktop. On Fullscreen, the window (rather than the desktop) is taken over, and it is up to the host to render the contents as fullscreen. To mitigate the impact on Desktop's implementation, browser-fullScreenAndPointerLock.js is forked and removes the dependencies on browser.js. These two files will be rationalized at a later time. Differential Revision: https://phabricator.services.mozilla.com/D48913 --HG-- rename : browser/base/content/browser-fullScreenAndPointerLock.js => browser/fxr/content/fxr-fullScreen.js extra : moz-landing-system : lando
