I wrote a java applet that accesses the file system using AccessController.doPrivileged. it workes on all windows, and browsers, except FF on win 7.
running as administrator solves the problem, however, it is not needed for IE or Chrome, only for FF. tested on win 7 with: FF: 16, 17 18 java: 1.6, 1.7 32 bit.
the code tries to write a file to the default sandbox location, and of course that it is signed. (otherwise it wouldn't have worked in other browsers):
AccessController.doPrivileged(new PrivilegedAction<String>() {
public String run()
{
String filename = UUID.randomUUID().toString();
File newTextFile = new File(filename);
String filepath = newTextFile.getAbsolutePath();
System.out.println(filepath);
fileWriter = new FileWriter(newTextFile);
fileWriter.write(content);
fileWriter.close();
return "a";
}

A good place to ask advice about web development is at the MozillaZine "Web Development/Standards Evangelism" forum.
The helpers at that forum are more knowledgeable about web development issues.
