-// This pref governs whether we attempt to work around problems caused by
-// plugins using OS calls to manipulate the cursor while running out-of-
-// process.  These workarounds all involve intercepting (hooking) certain
-// OS calls in the plugin process, then arranging to make certain OS calls
-// in the browser process.  Eventually plugins will be required to use the
-// NPAPI to manipulate the cursor, and these workarounds will be removed.
