Desktop resolution provides about 5 bits of identifying information, and window and decoration sizes provide yet more. This information is available both through window.screen and [https://developer.mozilla.org/En/CSS/Media_queries CSS media queries]. | |||
There are a couple of options for anonymous browsing mode to handle this data. One would be to lie, and to present websites with a common desktop resolution, and round the reported browser resolution to some multiple of pixels. | |||
A another option would be to tell websites that the desktop resolution is the render window, and resize the render window to either a popular common resolution, or to a multiple of 50px. The downside of this approach is that it has shortcomings when the window is maximized, because window decoration and scrollbar sizes will prevent rounding to an actual multiple of 50px. | |||
