Opera is a non-sense web browser. When updating, you have to download the full web browser, not just the updating itself, but the whole new release browser. It's annoying and useless. x-( Now Opera 9.51 is available. So, will I wait to Opera 9.51 for U3 and download it again (because I already have Opera 9.50)?! x-( Mozilla Firefox is tooooo muuuccchhh better: a couple of days ago the 2.0.0.15 version has been released and it includes the U3 Smart build, so I just installed the updating only, not need to download Mozilla Firefox fully again (it was less than 700 KB). I'm just wondering what about Mozilla Firefox 3.0 for U3 Smart (I mean an official build from Mozilla). :-( I hope it is available very soon. In the mean time, remember there's an unofficial Mozilla Firefox 3.0 build for U3. You can download it from here: http://www.4shared.com/file/52168676/ad82dc92/Mozilla_Firefox_3__en-US___U3_Smart_Build_.html?dirPwdVerified=e0900e13 Smackers!
