What came as a surprise was the name of a few of the new extensions – namely those from Bing and Amazon. You’ll also find extensions for MLB.com, the New York Times, Twitter and eBay. You can access the new extensions within the browser, and install with a single click. You’ll not have to restart Safari for your choices to take affect, unlike what you have to do with Firefox.
Manage your addons within your Safari window and update with a single click. Disable or enable individual extensions or turn them all off at once. Each extension comes with a signed, digital certificate from Apple to “prevent tampering.” This also verifies that updates come from the original developer. Your extensions are also sandboxed. This will keep them from being able to access information on your system, and disallows communication with websites other than those specified by the developer.
