I use google chrome newest version because of:
Super speed,start pages and load sites,videos,images REALLY VERY QUICK!
He is safe too!
And that is all what i need from a navegator.
I dont use mozila or ie8 because:
Mozila slow loading,almost slow and have any errors...
Im not very sure if he is safe.
IE8 is just the worst navegator...
very slow in everything
and safe
