no longer accepts outerWidth/outerHeight features


Categories: DOM

Releases: Firefox 80


Previously in Firefox, it was possible to specify outerWidth and outerHeight as part of the method’s window features parameter. These non-standard size features corresponding to the window.outerWidth and window.outerHeight properties are no longer available to web content as of Firefox 80. Since no other browsers support these features, the compatibility risk should be minimal.
