So if people abandoned Chrome and Safari for Firefox, wouldn't Firefox be the new IE? I don't remember IE being open source and community-developed like Chromium which Chrome is based off of. I use Chromium on Linux and while there are a few things to complain about, it has been a pretty positive experience overall and worked better than Firefox.
