Abstract: A tool configured to build a cross-browser toolbar is provided. The tool includes a processor; and a memory coupled to the processor and configured to store at least instructions for execution of a wizard program by the processor, the wizard program causes to: receive an input identifying at least user interface elements and event handlers respective of the user interface elements, the input further identifies at least two different types of a web browser on which the toolbar can be executed; generate respective of the received input a toolbar render object, a script file, and at least one toolbar library for each type of web browser; and compile the toolbar render object, the script file, and the least one toolbar library into an installer file.

Abstract: A method and system for web browser agnostic functionality extension. The method comprises injecting, to a web-page requested by at least a web browser executed by a client system, a bootstrap script for execution of at least an extension to the web browser; retrieving an extension script by means of the bootstrap script, wherein the extension script is executed in the web page; and establishing a two-way communication channel between the bootstrap script executed in the web browser and an extension engine, wherein events generated by either the extension engine or the extension script are communicated over the two-way communication channel, wherein the events generated by the extension engine allow to at least modify content of the web page, thereby extending the functionality of the web page.

Abstract: A method for customizing the functionality of a web-browser extension by installing widgets in the web-browser extension. The method comprises obtaining a manifest file of a new widget from a web server hosting the new widget; extracting an address designating a location in a secured repository of source files of the new widget; retrieving the source files of the new widget; and loading the source files of the new widget to the web-browser extension.

Abstract: A cross-platform toolbar and method thereof is disclosed. The toolbar includes a toolbar render object defining at least user interface elements of the cross-browser toolbar; a script file defining at least event handlers associated with the user interface elements; toolbar libraries including at least application programming interfaces (APIs) and script files supporting a specific web browser type; and a unique dynamic-link library (DLL) file assigned with the toolbar libraries and the script file.
