I do know that the latest Firefox beta, 3.5b4, has been running smoothly around the clock, at least for me. Available here. And as previously indicated, I will indeed try Opera when I get some "spare" time.
FWIW, this sociology of browsers from Marty Manley:
Am testing a site these days, so I keep 3 browsers open: IE, FF 3.0.1 and Chrome. In two days, I have had four hard FF crashes -- unheard of. FF also lost track of all saved passwords, although it recovered (maybe thanks to Xmarks).
BTW, Chrome seems ever stronger. If this were college, IE would be the entitled rich kid who acts smart, but isn't, Firefox the impressive high achiever who is actually a bit lazy and dilettantish, and Chrome the kid who works nights to pay bills, is rock solid, and is steadily getting stronger and stronger.
Or, if you prefer, George Bush, Bill Clinton, and Barack Obama. As to Opera -- the garden variety A student of sound quality but without a compelling or differentiating architecture -- I think she makes a fine Secretary of State.
