Activities
Activities are contextual services to quickly access a service from any webpage. Users typically copy and paste from one webpage to another. Internet Explorer 8 Activities make this common pattern easier to do.
Activities typically involve two types of scenarios: “look up” information within a webpage or “send” web content to a web application. For example, a user is interested in a restaurant and wants to see the location of it. This is the form of a “look up” Activity where the user selects the address and views an in-place view of the map using his favorite map service.
WebSlices
WebSlices is a new feature for websites to connect to their users by subscribing to content directly within a webpage. WebSlices behave just like feeds where clients can subscribe to get updates and notify the user of changes
Favorites Bar
In Internet Explorer 7, the Links bar provided users with one-click access to their favorite sites. The Links bar has undergone a complete makeover for Internet Explorer 8. It has been renamed the Favorites bar to enable users to associate this bar as a place to put and easily access all their favorite web content such as links, feeds, WebSlices and even Word, Excel and PowerPoint documents.
Automatic Crash Recovery
Automatic Crash Recovery (ACR) is a feature of Internet Explorer 8 that can help to prevent the loss of work and productivity in the unlikely event of the browser crashing or hanging. The ACR feature takes advantage of the Loosely-Coupled Internet Explorer feature to provide new crash recovery capabilities, such as tab recovery, which will minimize interruptions to users? browsing sessions.
Improved Phishing Filter
Internet Explorer 7 introduced the Phishing Filter, a feature which helps warn users when they visit a phishing site. Phishing sites spoof a trusted legitimate site, with the goal of stealing the user?s personal or financial information. For Internet Explorer 8, we are building on the success of the Phishing Filter with a more comprehensive feature called the “Safety Filter.”
