[ad_1]

What is Flash cookie? What is a Silverlight cookie? And what Browser Independent Cookies? The third question (last) is the answer to the first two questions. Flash cookies are small files that store a large amount of information about you. It’s the same with Silverlight cookies (which are currently not supported). Are browser independent cookies harmful? We will find out if they are there after examining how they are used. What does Flash cookie do? Let’s take a look at these special cookies, what they do if they are bad and how to remove them if necessary.

Browser independent cookies

Browser cookies – what are they for?

You already know that different websites store data in the form of cookies on your computer. These cookies are usually designed to quickly navigate to the website the next time you log in. Some of them track cookies and some track third-party cookies, which are used when the website uses third-party elements such as Google search or Disqus comments. system.

Cookies are known to have a short lifespan and expire after a few hours or days. Important types of cookies are those that store your registration information so that you do not have to enter the same information over and over again if you regularly visit a website. All others can and should be removed regularly to keep your computer clutter-free, if not for privacy reasons.

These are regular HTML cookies designed to store information for some time and have expired. As you continue to visit the site, new cookies are created. These cookies are small and not particularly dangerous unless someone else is using your computer. Typically, login cookies are set when you select remember me when you enter any website. It is entirely up to you whether you want to allow login cookies – depending on how you use / share your computer.

Browser-agnostic cookies: what are Flash or Silverlight cookies

Flash and Silverlight cookies are independent of the browsers you use to access the Internet and are therefore referred to as browser independent cookies. So what does this mean?

Flash cookies are slightly larger than regular HTML cookies. Flash cookies (and sometimes Silverlight cookies) are used to store information about your games, online movies, etc. The original purpose of developing such cookies was to allow you to resume watching a movie on, say, YouTube. from where you left it. Other cookies will store your game progress, etc. They also store some other data, such as where you left watching the movie (time / search progress), what resolution you used, what volume level you set, etc. So that you can just go to the website and pick up where you left off without having to adjust sound, resolution, etc. every time.

IMPORTANT: Unlike HTML or browser-specific cookies, most Flash and Silverlight cookies do not expire. This means that your data is kept almost forever: until you format your computer or delete it using one of the methods mentioned below.

Are browser independent cookies dangerous?

The main feature of Flash and Silverlight cookies is that they are not associated with any particular browser. This means that when you delete your browsing traces from your computer using a third-party application such as CCleaner, browser-independent cookies are not deleted.

As such, Flash and Silverlight cookies, also known as browser independent cookies, are not a problem, but they help speed up access to everything they are linked. For example, they can help you watch an online movie from where you left it, or resume the game without losing your previous progress.

Thus, it can be said that Flash cookies are not dangerous. They actually contribute to a better user experience and that is what they are made for. But there is always exploitation – for both HTML cookies and browser independent cookies. And in the latter case, the chances of exploitation are higher, since they are not easy to remove.

Browser independent cookies can be used for marketing

It happens. Browser-independent cookies on your computer are used by third-party applications hosted on different websites to track your movement. These cookies provide information about all the social networks you use and how often. Third party marketing companies track you online by accessing these cookies.

Since the IP name of your computer is associated with these cookies, it is not difficult for them to uniquely identify you when you visit the website. All they have to do is run a search matching the name with those in their database. Based on all of this, you can create a good profitable profile that includes your browsing preferences, your purchases, and other online habits. A good, complete profile is often sold to various advertising companies, including some of the major search companies.

How to delete browser-agnostic cookies

Internet Explorer can remove Flash cookies subject to certain conditions. Here is a post on how to delete Flash cookies using IE. Adobe offers a small utility that downloads to your computer and removes local Flash cookies. Here’s a post on how to use the Adobe Cookie Manager.

TO delete Silverlight Cookies, you can visit any web page that contains a Silverlight application. Right-click the Silverlight application and select Silverlight from the drop-down menu. Then select the Application Vault tab. Delete all contents of this field. These Silverlight cookies are usually found in C: UsersUsernameAppDataLocalLowMicrosoftSilverlight folder.

You can also manually delete these cookies. To do this, open the explorer. Go to the “Users” section and then to your user profile. Open the Application Data folder. You may need to make hidden files and folders visible before you can view the application data folder. Check the Macromedia folder in all the different profiles you find there – roaming, local, etc. In the Macromedia subfolders, look for files with the SOL extension. Delete all files with the extension to remove Flash cookies.

This explains browser-independent cookies and how to remove them. It also creates an opportunity for discussion as to whether browser-independent cookies are actually dangerous, and if so, to what extent. I created a batch file to delete Flash cookies on every login. But do I really need to use it every time? Let me know your thoughts on this. Another question that comes up here is that even if we use a proxy, will websites be able to recognize the computer if they find Flash cookies stored locally?

Thoughts!?
