[Users] page layout scrambled in 3.3?

[Gianluca Cecchi]

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:

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
