Mmmm, extensiony goodness for Safari.
ClickToFlash is particularly welcome because it will automatically get the H.264 version of a video when available.
Firebug Lite for Safari isn’t as nice as Firebug but still handy and likely to evolve.
BetterSource pretty much completely rocks.
Duplicate Tab Button is a handy way to keep your place when editing.
Flickr breaks ExifExt unfortunately.
BuiltWith is actually quite handy. One-Click Bozo ^M^M ….IIS detection. 😉
