528. Briefly: Setting up 64 bit pre-built firefox (25) binaries on debian

/usr/local/lib is just a suggestion (and probably not a very good one).

Anyway, here's the quick and easy way to get set up with 64 bit firefox. Start it by calling firefox25

mkdir ~/tmp
cd ~/tmp
wget ftp://ftp.mozilla.org/pub/firefox/releases/25.0/linux-x86_64/en-GB/firefox-25.0.tar.bz2
tar xvf firefox-25.0.tar.bz2 
cd firefox/
sudo mkdir /usr/local/lib/firefox-25.0
sudo cp * -R /usr/local/lib/firefox-25.0
sudo ln -s /usr/local/lib/firefox-25.0/firefox /usr/bin/firefox25
