Debian etch 2.6.17-2-amd64 with a 32 bit sid chroot under /var/chroot/
firefox installed in chroot by chrooting into it and then using apt-get. Same method used to install mplayer, helix player, opera & others.
Started via schroot as usual user in 64 bit environment results in nothing...no firefox, no failures, no errors..just another prompmt line.
Same deal for mozilla.
Although I call it firefox it's really iceweasel but I've been down the '/usr/bin/iceweasel' root.
Anyone know what makes firefox so picky or is it just another reason to use Opera which is even has sound on youtube (woot woot for my teenage kiddies).
schroot -c sid32 -p firefox
