Abstract
There is disclosed a method of preventing privileged web browser extensions installed in a web browser from interfering in interactions between a user of the web browser and a web application server accessible via the web browser, the method including transmitting a web browser-intelligible file to the web browser (including a custom element designating an enclave portion); creating a sandboxed page; copying at least part of the enclave portion to the sandboxed page to create a local enclave; embedding the sandboxed page in a first iframe for rendering; embedding the first iframe in a second iframe; providing an API for the local enclave using web-accessible resources for access to entities outside the local enclave; providing a software agent in the second iframe to act as a proxy between the first iframe and external entities; and encapsulating the second iframe in a shadow document object model associated with a host page.
