Abstract: A web page is composed using a browser that displays an authoring web page containing an authoring tool embedded in the authoring web page. The authoring web page, as displayed in a browser window, includes a web page editing region that displays a web page under construction. The web page editing region further includes one or more user-specified instances of structured fields, each instance responsible for hosting content entered directly by the web page author through the browser window or identified by the web page authoring using the authoring tool. A composed web page is published, for example on the Internet. Thereafter, the composed web page can be rendered in a browser window of any client computer or device in a style consistent with the user-entered content in the web page editing region.

The method may further include receiving, by the first extension process via the public messaging interface, a messaging request from the second extension process, the messaging request including a unique extension ID of the second extension process. The method may also include determining, by the public messaging interface, whether to accept or reject the messaging request based on the first unique extension ID.

Abstract: An extension schema validator may be executable within an extension process of an extension of a browser application, and may be configured to validate the extension with respect to an extension application program interface (API) that is provided in conjunction with the browser application for implementation of the extension. A browser schema validator may be executable within a browser process of the browser application, and may be configured to validate the extension with respect to the extension API. Successful validation of the extension by the extension schema validator prior to attempting validation of the extension by the browser schema validator may be required.

Abstract: A method and system for monitoring events related to web browser extensions includes storing a set of events for which a browser extension integrated in a web browser application registers a listener. The browser extension integrated in the web browser application is executed. Upon the occurrence of an event related to the browser extension, an invisible event page associated with the browser extension is loaded if the event is one of the set of events. Using the invisible event page, a function related to a visible object of the browser extension is executed. The invisible event page is unloaded from the browser after receiving an acknowledgement from the browser extension.

Abstract: A method for installing an offered web application or browser extension in a web browser includes receiving a user action on a website located at a first internet domain. Information about the offered web application or browser extension not currently installed in the web browser is displayed in response to the user action.

Abstract: According to one general aspect, a computer-implemented method may include receiving, at a server, a request from a computing device for an executable installation file. The executable installation file may be configured, when executed on the computing device, to install a web browser application on the computing device. The request may be associated with a specific network resource location that is hosted by the server. The method may include, in response to receiving the request, obtaining the executable installation file, dynamically incorporating a data file into the executable installation file. The data file may include a browser extension definition for a browser extension corresponding with the specific network resource location. The executable installation file, with the incorporated data file, may be further configured, when executed on the computing device, to install the defined browser extension on the computing device.

Abstract: Annotations relating to web sites may be based on blog posts relating to the web sites. A user viewing a web site may concurrently view related blog posts about the web site. More particularly, in one implementation, a method includes detecting when a user visits a web page and receiving, in response to the detection, a group of blog posts that link to the web page. The method further includes displaying an indication of the group of blog posts to the user while the user is visiting the web site.

Abstract: A computer-implemented method includes setting minimum boundaries for a pop-up window based on content, displaying the content in the pop-up window, receiving an input to change a layout of the content, calculating new minimum boundaries for the pop-up window based on the layout change, resizing the pop-up window using the new minimum boundaries and displaying the content in the resized pop-up window.
