I wrote a script to show a grid overlay using a javascript bookmarklet. Now OS X throws an error (NS_ERROR_DOM_BAD_URI) when I try to load the script from a local path (file:///xy). Windows XP (in Parallels) doesn't have this problem. Loading it from a webserver works on OS X, too.
Is this related to WebKit and Gecko, to OSX or to something else? Thanks, Thomas
