There are many web browser available and each of them have their own mechanism of tracking history and cookies and also deleting them when needed. The problem with cookies is that it enables your Internet surfing to be tracked. Privacy Agent is the freeware app which enables you to enjoy the benefits of the Internet with the knowledge that your privacy is protected. Privacy Agent works with all browsers including IE9, Firefox, Google Chrome and Safari and deletes history of the websites you have visited.
Once installed, just run the scan and the app fetches all the history details. The details include cache, cookie history, download manager list, form history, passwords and much more. The app will close all browser before starting the scan, so save your work before starting.
Once it generates the report, you can select the items which needs to be removed. While it allows selectively removing content, it does not allow selective scanning from browsers which would have come handy. The app is supported on Windows 7, Vista and XP (both 32 bit and 64 bit).
Overall, Privacy Agent does the job pretty neatly to wipe all the traces of your internet activity.
