Changes

The Chrome extension API was designed to work well with process separation and we are certainly taking inspiration from it and copying functionality where it makes sense. However, there will be differences. We won't implement all of Chrome's APIs, and we will . And Chrome is unlikely to implement our own some of the APIswe add. Imagine the APIs as a Venn diagram. In the middle are cross-browser APIs for content scripts, tabs, and windows. In the Firefox side are APIs for toolbars and sidebars. On the Chrome side are APIs for Google's cloud services.
