I think that Firefox should be replaced with Swiftfox (an optimized, proprietary version of Firefox). Link: http://www.getswiftfox.com
For me it is faster than FF.
For people that might bitch about it being closed source theres an Open Source counterpart of SF. It is called SwiftWeasel.

They are optimized in the same way, but with SW it has Pango render Unicode Fonts better. So Unicode looks better under SW rather than SF.
