Personally i hate firefox'es downloader, otherwise its not too bad. STILL=>
Opera is still WAY better. Why:
> better download manager.
> widgets are more user friendly than plugins.
> Fastest and most secure browser in the planet.
> PASSES THE ACID2 TEST
Take the test with your favorite browser: http://www.webstandards.org/action/acid2/
> has an inbiult mail client, popup blocker, BITTORRENT support, RSS READER and so on and so forth.
