Internet Explorer 8, now in RC1, will come with a new feature called InPrivate. This will allow you to browse the web without storing data about your browsing session. Learn about Internet Explorer 8 InPrivate.
Important! This does not mean your IP address is hidden!
The idea was first introduced by Google Chrome and called Incognito Mode. The same feature will be implemented by Firefox 3.1 under the name of Private Browsing.
Here is what Microsoft says about InPrivate:
When checking e-mail at an Internet café or shopping for a gift on a family PC, you don’t want to leave any trace of specific web browsing activity. InPrivate Browsing in Internet Explorer 8 helps prevent your browsing history, temporary Internet files, form data, cookies, and usernames and passwords from being retained by the browser, leaving no evidence of your browsing or search history.
In other words, the browser will not store any data about your online activities.
You can start InPrivate Browsing by opening a new tab and selecting Browse with InPrivate or selecting it from the Tools menu. Internet Explorer 8 will launch a new browser session that won’t record any information, including searches or webpage visits. To end your InPrivate Browsing session, simply close the browser window. Once again, this is not a method to hide your IP address!
Internet Explorer 8 InPrivate Filtering
Internet Explorer 8 comes also with another feature: InPrivate Filtering. This is designed to watch for and block only third-party content that appears with a high frequency across sites you visit. This means that it also blocks any tracking code that may be inserted in the pages you visit.
InPrivate Filtering is off by default and must be enabled on a per-session basis. To use this feature, select InPrivate Filtering from the Safety menu. To access and manage different filtering options for Internet Explorer 8, select InPrivate Filtering Settings from the Safety menu. To end your InPrivate Browsing session, simply close the browser window.
Enhanced delete browsing history
In Internet Explorer 8 you can now choose to preserve cookies and temporary Internet files for sites in your Favorites folder. This helps to protect your information and privacy while preserving your data on your trusted favorite sites. Your preferences and cookies are preserved, helping you to get to your trusted sites faster with greater confidence.
