i dont like change so i will keep my firefox. though i do use chrome on low end hardware.
also a big thumbs down for not using firefox 4 in the benchmark, i would also have looked at memory usage.
as for ads, to hell with them. i lost my patience with add banners when they started having sound. most of the time when you use a computer you really want it to be quiet. so when some dumbass pops up and tells me i have been selected to receive a million dollars and a ferrari. needless to say it was a little more than distracting. the ads should fit the media. tv has sound and images so its ok if adds have sound (though lately i find a great many channels turn up the sound greatly on commercials so you have to ride the remote to constantly normalize your volume, i guess il just have to torrent tv shows now), radio has sound, but most of the time the internet is silent and the adds should reflect that. granted a site that plays music could do audio adds, or a site that plays videos could put tv commercials in for all i care (so lontg as they can keep the levels in tune with the content).
now the other reason i block ads on every computer in the house, is limited throughput. 512k is not suitable for loading these flash, sound, and video laden banners that have the compression turned off so as not to make the ads look bad. when you spend 15 seconds loading ads and 5 seconds loading content, that is ridiculous. ads should be size-proportional to content. having to load a 2 meg ad when looking at a 2k page should be banned. ads are far more evil that any proggie meant to block them. they have been scientifically proven to destroy minds and corrupt our children (no i will not source it), stop the ads before its too late!
