User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Put something like this in an html file on your LOCAL (127.0.0.1) server: <html><head></head><body> <br><br> <a href="file:///c%3A">Browse Via OS</a> <br> <br><br> </body></html> The file needs to be served from a local web server (not simply opened locally, e.g., via drag & drop). The link should work but it doesn't. Mozilla seems to not be checking if the source page is local (it is) and then allowing the file:// scheme to function, it seems instead to require the user to start off in the file:// scheme for such a link to work. Note if you right-click and select "Copy Link Location" and paste that into the location: field the directory is shown. Reproducible: Always Steps to Reproduce: 1. Create the file like the one mentioned in Details, above. 2. Make sure the file is served by an httpd server. 3. Access the file LOCALLY. 4. The link doesn't function. I think it should (does in IE). Actual Results: No action occurs in the browser. Expected Results: The linked-to local directory should open in browse mode just as if you entered (or copied) the location into the "Location:" field in the browser.
That is by design and can be toggled by a pref. See the Release Notes. (same for 1.5) http://www.mozilla.org/releases/mozilla1.6b/known-issues.html#psm So the bug is invalid.
