Apple’s vice president of OS X Product Marketing, Brian Croll said:
Safari 5 has been a big hit, and user response to the innovative new Safari Reader has been fantastic.We’re thrilled to see so many leading developers creating great extensions and think our users are going to love being able to customize Safari.
The new Safari Extension Gallery allows user to find extensions for the applications they want. Extensions range from toolbars that displays live web feeds to sophisticated programs that filter web content. Apple had invited developers to submit their extension about two weeks ago, that is why the gallery is now full of a significant library of plug-ins. The extension gallery already has some default extension from companies like Twitter, The New York Times, The Weather Channel, Amazon, Bing and eBay.
Safari Extensions works with both Mac and Windows version of the browser.
