To get an extension for your Safari, you can open the Safari Extensions Gallery from the browser menu, search for the one you need, and click Install Now button next to the extension you wan to have. All the extensions provided there are signed and hosted by Apple, and Safari will update them automatically. Also, you can directly download the .safariextz file from your favorite developer and double click to install it.
