A new version of the incredible Flock browser is now available. For those that are running it on an ubuntu system you most likely need to manually update.
Download Flock 0.7.6
Unpack latest version (should be on Desktop): sudo tar -C /opt -xzvf flock-*.linux-i686.tar.gz
Enjoy!
If this is your first installation of Flock on Ubuntu visit my previous post with complete steps.
