I want to be able to really fine tune/customize firefox, but many of the changes I want to make are only available thru 'about:config'. An example of such a change -- how to force new tabs to open blank -- took quite a bit of searching and knowing what question to ask or how to phrase it. Is there a list of all the 'about:config' commands, and if so, where do I find/get them? Is it just a printable list (acceptable, but just...), a basic searchable database (better, but probably still have to know/phrase a question), or best yet, a keyword searchable db with both of the previous options? Also, is this putative list version specific, or is it constantly updated with a mix of old and new commands? I realize the risk of severely damaging the firefox installation, and am prepared to take it, as I think I'm reasonably cautious, and would check out any truly questionable changes before making them.
