Open the Safari app on your iPhone. Tap and hold the tabs icon, which looks like two overlapping boxes and appears in the bottom-right corner of your screen. In the pop-up menu, tap “Close All Tabs.” Confirm that you want to close all the open tabs in the browser by tapping “Close All Tabs.”

Automatically fill in your information in Safari on iPhoneIn the Safari app , use AutoFill to automatically fill in credit card information, contact information, and user names and passwords.

Most browsers do give focus to a button being clicked, but Safari does not, by design.

not all modern implementations have implemented this specification correctly (e.g., Safari)

This section defines three signature algorithms based on the RSA encryption process described in Sections 8 and 9. The intended use of the signature algorithms is in signing X.509/PEM certificates and certificate-revocation lists, PKCS #6 extended certificates, and other objects employing digital signatures such as X.401 message tokens. The algorithms are not intended for use in constructing digital signatures in PKCS #7. The first signature algorithm (informally, "MD2 with RSA") combines the MD2 message-digest algorithm with RSA, the second (informally, "MD4 with RSA") combines the MD4 message-digest algorithm with RSA, and the third (informally, "MD5 with RSA") combines the MD5 message-digest algorithm with RSA.

Accessing a Webpage

In Share extensions (on both platforms) and Action extensions (iOS only), you can give users access to web content by asking Safari to run a JavaScript file and return the results to the extension.

On both platforms, your custom JavaScript class can define a run() function that Safari invokes as soon as it loads the JavaScript file. In the run() function, Safari provides an argument named completionFunction, with which you can pass results to your app extension in the form of a key-value object. In iOS, you can also define a finalize() function that Safari invokes when your app extension calls completeRequestReturningItems:completion: at the end of its task. A finalize() function can use items your extension passes in completeRequestReturningItems:completion: to change the webpage as desired.

Create a JavaScript file that includes a global object named ExtensionPreprocessingJS. Assign a new instance of your custom JavaScript class to this object.

At various times, such as when a tab is added, Safari will ask you to validate the command. If there is any possibility that the command could be invalid, you should add a listener function for the "validate" event.
