Hello, On Windows chromium-based browsers, the links with linux-style urls : "/path/to/file" are expanded to "/<current device letter>/path/to/file" which can prove pretty handy. Example: A local "D:\html\index.html" file declaring a '<script type="text/javascript" src="/js/file.js"></script>' will have the "src" expanded to "file:///D:/js/file.js". Of course on this particular example, it would be easy to use relative paths but "absolute" paths can be useful when referencing shared common files (javascript, css, ...). This way, an html file can be tested locally (without a local server) before being deployed as-is on a server. Unfortunately, on Firefox there seems to be no such mechanism, unless I have missed something... Is there any plan to add such a feature?
