37            <h3>Why doesn't my test suite run under JSCoverage in Firefox 3?</h3>
38    
39            <p>
40            Firefox 3 introduces <a
41            href="http://tech.groups.yahoo.com/group/jsunit/message/1075">new
42            security restrictions</a> on local files.  Depending on the way your
43            test suite is organized, this may cause problems for JSCoverage.
44            (You may get the error "uncaught exception: Permission denied to get property Window._$jscoverage".)
45            There are several workarounds:

49            <li><p>Place your files on a web server instead of loading them from the file system.
50                This is usually the simplest solution.</p>
51            <li><p>Organize your HTML files in your test suite in a flat directory structure.  For example, suppose that
52                you instrument your test suite with this command:</p>
53    <pre>
54    jscoverage src instrumented
55    </pre>
56                <p>If all your HTML files are located directly under the <code>src/</code> directory (i.e., not in a
57                subdirectory of <code>src/</code>), then you should not have any problems using Firefox 3.</p>
58            <li><p>Set the <a href="http://kb.mozillazine.org/Editing_configuration">Firefox preference</a> named
59                <code><a href="http://kb.mozillazine.org/Security.fileuri.origin_policy">security.fileuri.origin_policy</a></code>
