I had some trouble installing Google Chrome within firefox. It downloaded the .rpm file to /var/temp, but was unable to install it with gPackageKit due to "insufficient permissions". If you have this error, or just want an easier way to install Google Chrome, here is how:
I had an issue as well with my package manager not automatically finding one of the dependencies, but this problem could have been on my end. To be safe, install the "lsb" package from your package manager.
This one-stop-shop command (as root) will Download and install the x86 version of Google Chrome.
wget https://dl.google.com/linux/direct/google-chrome-stable_current_i386.rpm && rpm -i google-chrome-stable_current_1386.rpm
For the x86_64 version:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm && rpm -i google-crhome-stable_current_x86_64.rpm
Of course, both of these commands assume that you have read the license agreement here: http://pastebin.com/ExXM86Y1
