Firefox loading links to local pages

External info for Firefox: Links to local pages don't work: disabling the security check for certain sites When you want to be able to follow links in Firefox to files on a local computer or an intranet you have to allow those computers explicitly, otherwise the links will not work. I you try it and open the Error Console you'll see something like ‘Security Error: Content at may not load or link to file:///my-folder/my-file.html’.
