Looking for an ARD/ Unix command to clear firefox history/cache on a mac I'm trying the following but not having any success in seeing anything cleared:

rm -R /Users//Library/Caches/Firefox/Profiles/.default/Cache

Thanks!
I think you're looking in the wrong folder.  The more recent versions of Firefox put it here.  You may want to alter your command slightly to delete folders as well. 

rm -rf /Users/&lt;username&gt;/Library/Caches/Firefox/Profiles/&lt;xxx&gt;.default/cache2
