Abstract: An electronic device displays a content region including first content that contains an image; and, while displaying the first content, detects an input at a location that corresponds to the location of the image. In response, the electronic device, in accordance with a determination that the input includes an intensity above a respective threshold and that the image is associated with a link to second content that is different from the first content, displays a preview of the second content while maintaining display of at least a portion of the first content in the content region; and, in accordance with a determination that the input includes an intensity above the respective threshold and that the image is not associated with a link to additional content, displays an enlarged version of the image while maintaining display of at least a portion of the first content in the content region.

Abstract: Systems, methods, and computer readable media to improve the operation of graphics systems are described. In general, techniques are disclosed for determining the computational need of GPU-centric elements executing from within pages of another application, selecting one or more GPU's appropriate to the need, and transitioning the system to the selected GPUs.

Abstract: An electronic device, while displaying a user interface that corresponds to at least a portion of a web page on a display, detects a touch input on a touch-sensitive surface at a first location that corresponds to the displayed portion of the web page on the display. While detecting the touch input on the touch-sensitive surface, the electronic device detects an intensity of the touch input on the touch-sensitive surface, determines whether the intensity of the touch input on the touch-sensitive surface has changed from below a first intensity threshold to above the first intensity threshold, and in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, generates a force down event that is distinct from a mouse down event.

Abstract: In some implementations, a website can be certified by a push notification service operator to send push notifications to user devices. A web browser on the user's device can communicate with the website to advertise the user device's ability to receive push notifications. The website can provide to the web browser a certificate indicating that the website is authorized to utilize the push notification service. If the certificate is valid and has not been revoked, the browser can prompt the user to allow push notifications from the website. If the user authorizes push notifications, a device token can be provided to the website that allows the website to send push notifications to the user device through the push notification service. In some implementations, the web browser can be configured to provide websites access to APIs for accessing information stored on a user device.

Abstract: Presenting snap-shots of plug-in content in user interfaces. Input to present a user interface that includes content obtained by executing a plug-in is received. In response, the plug-in is executed to obtain the content. An image representative of the content is identified. Then, the execution of the plug-in is terminated, and the image representative of the content is displayed in the user interface. In the user interface, an object selectable to present the content obtained by executing the plug-in is displayed. When a selection of the object is received, the execution of the plug-in is re-instantiated to obtain the content, and the content is displayed in the user interface in place of the image.
