Browser Cookies: What are They and How to Clear it

Web cookies are little files hide in a computer so that your browser and websites can track who you’re (in person), your browsing patterns, your buying habits, to log useful information like; your account names and passwords, for later retrieval. Although this may sound harmless but can threaten your privacy if an attacker tries to use them for malicious purposes.

Here you can learn to perform the most important task – how to clear cookies and cache – in all the most popular browsers.

Starting from the most-used browser – Chrome.

Throughout the guide, one can think of;

What Happens When You Delete Cookies?

Clearing cookies will log you out of every website you’ve logged in, even those where you checked “stay logged in or “remember me”; once you log-in back to a site, the website will recreate the deleted cookie.

When logged into an account, any settings you change are generally saved to your account data, these changes are often saved as cookies instead. Deleting cookies will remove all such settings, bringing your site back to the default, so you will need to re-customize the settings if desired.

Deleting cookies will also change your advertising experience.

What if you BLOCK cookies?

Once cookies are blocked, you’ll need to log in to the site every time you browse it. Some sites fail to keep you logged in even from one page to the next. Other websites will also display errors or not function correctly when cookies blocked.

So, what to do?

As a middle ground, choose to block cookies by default but do allow them for certain websites.

Is it a good idea to remove all cookies?

Yes, it is, especially if;

  • You logged in to any of your accounts on a public computer.
  • You don’t want websites to track you.
  • You’re encountering bugs in trying to load a website – saved files get problematic if the site introduces a new feature or update.
  • Your browser is slow; though browsers save cookies (only a few KB) to your hard drive, but often accumulates in piles.
  • You changed your credentials – where we choose (or need) to change passwords, presents a problem if we don’t clear cookies. Failure to do prevents a website from successfully authenticating for a service.

Want an Auto-check? Use Apps and Plugins

To make cookie management swept and easier, there are a host of apps and browser plugins that will give you a little more control of your web cookies; use CCleaner or Cookie AutoDelete – to clean excess files generated by your browser and other applications
