Safari is my favourite web browser, mostly because of how blazingly fast it is. Though I still end up doing a lot of web-development in Firefox, as a host to Firebug. The Web Inspector might soon change it.
This WebKit functionality is not enabled by default, but it's an easy fix:
defaults write com.apple.Safari WebKitDeveloperExtras -bool true
It is almost there! The major feature that's still lacking is the ability to edit DOM elements live (previews, mockups, or simply tests). Though otherwise it does everything Firebug does.
