Just received an email today from Google: This is great news, and once Google drops support for IE6, it will make a huge difference in the no more IE6 campaign.
my favourite browser is firefox it is very fonksionell so in my opinion google may profer to mozilla firefox..
yeah its because of some html and scripts issues.. besides they have a suggestion to update or use another browser to view the page/site..
That's the usually nature, previous things that are out of date, phasing out will eventually became history.
