I think the problem may be that it is impossible to install firefox 3.6 on ubuntu 12.04, because when run gives this error:
"/ opt/firefox3/run-mozilla.sh: 143: exec: / opt/firefox3/firefox-bin: not found"
I've done with this tutorial:
http://www.liberiangeek.net/2012/04/how-to-install-previous-versions-of-firefox-in-ubuntu-12-04-precise-pangolin/
To uninstall, bad installation with a deb package, which is where the problem has given me uninstall what I did was install it as normal sudo apt-get install firefox and then uninstall with purge
