Want to install flash player (FP) in my Slackware 12.0. FP asks for the install directory of my Firefox 184.108.40.206 browser and suggests it might be: /usr/lib/mozilla. AND I have such a directory. When I find / -name firefox I get 2 more which look viable: /usr/lib/firefox and /usr/lib/firefox220.127.116.11 (yes, 0.4). There is an executable firefox bourn shell in the latter.
Where is the Firefox install directory? How can I be sure??
