firefox 3.6 on fedora 23

I work on lots of legacy hardware that needs older browsers for ssl and plugins.

so I use a a old tarball of firefox 3.6 to get around most things.

#dnf install xulrunner-40.0-1.fc23.i686
#dnf install gtk2.i686

then

@WOPR1 firefox]$  su dracsucks
dracsucks@WOPR1 firefox]$ xhost +
dracsucks@WOPR1 firefox]$ cat /etc/redhat-release
Fedora release 23 (Twenty Three)
[dracsucks@WOPR1 firefox]$ LD_LIBRARY_PATH=/home/dracksucks/bin/firefox/ ./firefox-bin
