ease of use come with how used to a particular browser you are i guess. when i have to use chrome and i right click. well nothing is the same and i'm lost 
on a funny sidenote . i was messing about on a mac a few weeks back. i didn't know if i was coming or fucking going with the bastard 
The easy of use is, of course, relative. For me it's like a woman you know for years (yes nerd). Just like FF, you have Opera in all kind of flavors (Win, Mac, Linux, etc). There's always a learning curve involved and there is no such thing as a perfect browser. I've tried a dozen, but for me Opera is on top.
www.opera.com , give it a try and let me know.
