With Big Brother spying and advertising agencies attempting to give you targetted advertisements, protecting your privacy online is getting even more important than earlier. Meet the “Cookie”, the biggest helper to tracking your movement is sitting on your computer via your browser.
If you’ve never heard, here’s a direct definition from Wikipedia:
A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is a small piece of data sent from a website and stored in a user’s web browser while the user is browsing that website. Every time the user loads the website, the browser sends the cookie back to the server to notify the website of the user’s previous activity. Cookies were designed to be a reliable mechanism for websites to remember stateful information (such as items in a shopping cart) or to record the user’s browsing activity (including clicking particular buttons, logging in, or recording which pages were visited by the user as far back as months or years ago).
If you’re using Firefox, then you have many solutions that help protect your privacy. One really awesome solution is Self-Destructing Cookies.
Self-Destructing Cookies automatically removes cookies when they are no longer used by open browser tabs. With the cookies, lingering sessions, as well as information used to spy on you, will be expunged. Websites will only be permitted to identify you while you actually use them and can not stalk you across the entire web. This is the closest you will get to cookieless browsing without breaking every second site or tedious micromanaging.
The add-on identifies tracking cookies by their behaviour and so doesn’t require a blacklist to work. The add-on also supports localStorage and treats this just like a cookie jar that saves cookies temporarily when you visit the current site. When you close the last window of the site, the cookie jar will be emptied. This ensures that when you jump to the next site, the tracking cookie cannot be used because it no longer exists!
This add-on complements blacklist-based solutions such as Adblock and Ghostery very well. You can whitelist sites whose cookies and LocalStorage you would like to keep without an active tab in the Firefox cookie exception list, which can also be conveniently accessed from the add-on’s preferences, or an icon in the Add-on Bar.
