[Users] page layout scrambled in 3.3?

Firefox on CentOS 6.4 ( version firefox-17.0.8-1.el6.centos.x86_64) gives these kinds of layout, just after engine-setup phase. This is when selecting "Default" datacenter icon: https://docs.google.com/file/d/0BwoPbcrMv8mvVGhxck9kTGJtLXc/edit?usp=sharing This is when I select the main "System" icon: https://docs.google.com/file/d/0BwoPbcrMv8mvcU11czRsTW1yX1k/edit?usp=sharing the engine is freshly installed fedora 19 where to day I ran update and engine-setup after enabling beta ovirt repo (ovirt-engine-3.3.0-4.fc19.noarch installed) Anyone else? What would be recommended browser for upcoming 3.3 and its version? Thanks, Gianluca
