Delete Flash Cookies: The Hardly Known Step for Optimum Privacy

It is common knowledge that surfing the web will expose a user’s personal information compromising the safety and privacy of his or her files and computer. To maintain safety and security, a careful user will typically delete browsing history, files and cookies after a session on the internet. Since search engines keep the record of the visited websites, deleting the history or clearing the cache and cookies can be easily done through the tools tab (or equivalent) of the browser itself. For example, to manually erase the browsing history in Firefox, you can simply do the following steps.

  1. Click on the Tools tab located at the top of the browser’s window.

  2. Select Options and click on the Privacy tab.

  3. Click on the link “Clear your recent history”

  4. Choose the time frame that you want for deleting the history in the drop down box.



If you regularly do this clean-up process then kudos to you. You are one step ahead of the other users in keeping your computer secure. But simply removing your browsing history and cookies in the web browser does not give your computer complete protection. Average users always miss on one more step only because they are unaware of another type of cookies – the flash cookies.

Essentially, flash cookies, otherwise known as Local Shared Objects (LSOs), are cookie files used by Adobe Flash Player. That means Adobe’s well-known Flash plugin separately saves its own cookies from the normal browser cookies. For instance, flash cookies can save your settings and preferences when you are video streaming or playing online games. So even if you regularly clean your browser’s history and cache, a record of your online activity still exists if you do not delete flash cookies. And if you do not totally clear up your tracks, it is highly plausible for hackers to gain access to your personal data or cause damage to your files and computer. The sad part is only a few people even knows about the existence of flash cookies. But now that you are among those who have basic knowledge on these dangerous flash cookies, you are close to getting optimum privacy. For a thorough understanding, the list below shows all the facts about flash cookies followed by ways on how to manage or delete them.

Maintaining browsing security and privacy always depends on one’s level of knowledge.
