However, if I include the same link on a Web page, clicking on it yields no response. Reproducible: Always Steps to Reproduce: 1. Set up a Windows file share. Assume machine name FOO and share name BAZ. 2. Type the following into the Address Bar: file://///FOO/BAZ 3. Click on the link in the following HTML: <HTML> <HEAD><TITLE>This Is Broken</TITLE></HEAD> <BODY> <A HREF="file://///FOO/BAZ">This Will Do Nothing In Mozilla</A><BR> </BODY> </HTML> 4. Now repeat both steps in IE (any version since 3.0, at least). Actual Results: 2. Typing into Mozilla's Address Bar works fine. 3. Clicking on the link in Mozilla does nothing. 4. The IE test works fine. Expected Results: Steps 2 and 3 should have yielded identical results.
That is totally by design. A website should not have any access to load things from your hard drive. By loading things, websites may be get access to their contents which may lead to other bad security issues. That said, we should put up a dialog when this happens so that you know we're intentionally refusing to load it. *** This bug has been marked as a duplicate of 84128 ***
There are many discussions about this bugs are very easy to find. (Have you searched before you filed the bug ?) There is a way to disable this check with a hidden pref but that can open security problems. verified dupe
Of course I searched. Apparently, however, on insufficient criteria :)
