Additional Theme APIThe API around themes continues to grow, allowing you customize even more of the browser appearance. In Firefox 5. 8, you can now Reader Mode API Added to Tabs. The API available for interacting with tabs continues to grow. Firefox reader view or reader mode strips away clutter like buttons, ads and background images, and changes the pages text size, contrast, and layout for better readability. It can even read the page out loud to you, if you want. The image below shows a page that can be viewed in reader mode, indicated by the page icon in the URL bar circled in red. Clicking on the icon puts the page in reader mode, removing most of the page elements except the text and adding buttons to the left hand side that modify the reading experience. This powerful browser feature is now available via the Web. Extensions API. Improved web. Request APIExtensions can now easily get the entire URL ancestor chain, even in an HTTP environment. Request. on. Before. Request now includes another parameter in its callback object called frame. Ancestors. This is an array that contains information for each document in the frame hierarchy up to the top level document. Additionally, to enable proxy authorization to work smoothly,  web. Tasty Planet Back For Seconds Full Version No. Request. on. Auth. Required now fires for system events. If an extension has the correct permissions, it will be able to use on. Auth. Required to supply credentials for proxy authorization. Flexible XHR and Fetch Headers. When a content script makes requests using the standard window. XMLHttp. Request or window. API, the Origin and Referer headers are not set like they would be when requests come from the web page itself. This is often desirable in a cross domain situation so that the content script does not appear to come from a different domain. However, some sites only allow XHR and fetch to retrieve content if the correct Referer and Origin headers are set. Starting in Firefox 5. Web. Extensions API permits the use of content. XMLHttp. Request and content. Improved Content Security Policy CSP Handling. Work also continues in the Web. Extensions CSP area. Starting with Firefox 5. CSP of a web page does not apply to content inserted by an extension. This allows, for example, the extension to load its own resources into a page. This is a fairly large effort requiring some substantial architectural work. In Firefox 5. 8, the first part of this work has landed, permitting basic injection of content generated by DOM APIs. There will be follow ups for parser generated content and inline stylesheets and scripts. Setting the Default Search Engine. Automotive Expert Serial. Using chromesettingsoverride, an extension can now install a new default search engine by setting the isdefault key to TRUE. To protect the user, this cannot be done silently and the user will see an additional dialog that prompts them to confirm the change. The user will also see if their default search engine has been overridden in the Options about preferences page, which is explained in more detail below. User Notification of Extensions Overrides. As the scope and power of the Web. Extensions API increases, it is important to maintain the users security and privacy. In addition to the permission dialog that a user sees upon installation, Firefox tries to make sure that users are aware of which parts of the browser are under the control of an extension, and provide a way for them to revert back to default behavior, if desired. Firefox 5. 8 landed a couple of features in this area. First, when an extension has taken control of the New Tab Page, a notice is shown in Options about preferences along with a button to disable the extension. This is shown in the screenshot below. Along similar lines, if an extension has set a users default search engine, this will be shown on the Options about preferences page. Over the next few releases expect to see Firefox show even more areas where an extension is in control of a browser behavior along with options to revert back to a default state. Additional Privacy Controls. In keeping with Mozillas mission to protect an individuals online security and privacy, two new browser settings related to user privacy are now exposed via the Web. Extensions API.  Within privacy. Party. Isolate This preference makes the browser associate all data including cookies, HSTS data, cached images, and more for any third party domains with the domain in the address bar. Fingerprinting Browser fingerprinting is the practice by which websites collect data associated with the browser or the device its running on to personally identify you. This preference makes the browser report spoofed information for data thats commonly used for fingerprinting. Browser Action Fixes. A number of changes landed in Firefox 5. Browser Action buttons Support for PKCS 1. Security Devices. Firefox supports manual installation of external security devices via a dialog under the Options about preferences screen. Now, Web. Extensions includes API support for PKCS 1. Similar to native messaging and managed storage, a native manifest must be installed outside of an extension before the API become useful. Android. On Android, users get install time prompts for Web. Extension permissions, but under Firefox 5. Miscellaneous Changes. More to Come.
