Safari: You checked out the new features in Safari, you enabled extensions, but now what? You need some extensions to play with. Safari Extensions is an unofficial catalogue of available extensions to keep you updated until the official gallery goes live.
Apple won't be opening their extension gallery for Safari for a few months yet. If you want to play with extensions sooner rather than later Safari Extensions is an unofficial catalogue of available extensions.
The current offerings are small compared to the massive catalogues for browsers like Firefox and Chrome but with Safari 5 hot off the development press this morning we're not in any position to complain — especially in light of the fact that in the time it took to write this article the number of offerings doubled! Check out the extensions they have or submit extensions you've found in your travels. Safari Extensions is a free site and requires no registration. Thanks jwisser!
