Bug 1112424 adds an about:media page that gives debug information about HTMLMediaElements and in particular MediaSource objects that are live inside tabs. This patch adds methods to the MediaSource and HTMLMediaElement object to return the debug data as a string that gets displayed directly in the about:media page, inside a <pre> element. --HG-- extra : rebase_source : d655dc3d30a26846b965ceeda4849745aab7bef5
