I've started linking to files on my computer like this, 'Index of file:///Users/michaelo/Dropbox/KN' which works fine apart from the fact that this calls up all the hidden files, which do not want to see by default. There's a checkbox "Show hidden objects" which will hide these when unchecked. But settings are per folder and of course aren't remembered between sessions. Is there a way via about:config to hide hidden objects by default? TIA x MO
