Abstract: Methods and systems for associating, in a secure manner, a link between web sites (or other network resources) and installed applications. In one embodiment, a signed list of one or more URLs is downloaded and validated to establish an association, which is stored in a data structure, between a first application and a second application. In response to receiving a selection of a URL in the second application, comparing the selected URL to URLs in the data structure and displaying, in the first application, content of the selected URL in response to determining that at least a prefix portion of the selected URL matches one of the URL associated with the first application in the data structure.

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 various embodiments described herein, a content extension and programming interface enable third-party content extensions to supply transformation and filtering actions and associated criteria to native web clients on a system. In one embodiment, the native web client loads data for a third-party content filtering, blocking, or transformation extension and conducts extension defined actions without requiring additional intermediation by the third-party content. In one embodiment, a third-party application downloaded to a mobile or handheld device can include an extension data object that provides actions and triggers that are loaded by a native web client of the system. The third-party application is not required to execute continuously and can exit or be terminated once the web client retrieves the extension data object.

Abstract: According to one embodiment, in response to an inquiry received from a first application for an extension service associated with a first of a plurality of extension points of an operating system, a list of one or more extensions is identified that have been registered for the first extension point with the operating system, where the first application is executed within a first sandboxed environment. The identified list of extensions is displayed to prompt a user to select one of the extensions to be associated with the first application. In response to a selection of one of the extensions, the selected extension is launched in a second sandboxed environment. The selected extension and the second application were packaged in an application bundle, and when the application bundle was installed, the selected extension and the second application appeared in a registry of the operating system as separate applications.

Abstract: A host application executing on a client device includes a content processing extension that extends its functionality to process content items to a requesting host application executing on a client device. The content processing extension is an executable file that includes data conversion code and application code. The data conversion code, when executed in requesting host application, identifies content items provided by the requesting host application and formats the identified content items to be received by the content processing extension. The application code is native code executable by the host application associated with the content processing extension. The application code processes the results from execution of the data conversion and the identified content items in accordance with one or more functions of the host application, and returns the processed content items to the requesting host application via the content processing extension.

Abstract: The method for managing a plurality of windows of a browser application on an electronic device includes assigning a priority level to each process, including the browser application, running on the device, and distributing computing resources based on priority level. In response to receiving an action to open a window, the browser application starts the execution of a process for opening the window, associates the process with the window, and assigns a priority level to the process associated with the window. The browser application then monitors an activity level of each process associated with its windows. If the activity level decreases, the browser application assigns the process with the decreased activity level to a lower priority level. If requested computing resources exceed a maximum threshold, a process is selected from the lowest priority level processes, and the selected process is suspended.

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: Methods and apparatuses that maintain one or more data stores capable of storing local data in a device for loading a resource of a domain are described. The resource may be loaded to cause one or more data access operations on the data stores. Access to usage tracking data of the device from the domain may depend on at least one of the data access operations. The data access operations may be configured to block the usage tracking data of the device from the domain. The data access operations may be performed on the data stores for the loading of the resource. A web page may be presented to a user when the resource is successfully loaded.
