How To Configure Web Browser Security Settings
Regardless of the browser you are using, there are security settings that you need to know about in order to have greater control over your web browsing privacy and security.
In this section we look at how to configure privacy and security settings for:
- Browser Cookies
- Browser History
- Browser Cache
Browser Cookies
The main purpose of cookies is to identify users and possibly prepare customized Web pages for them. When you enter a Web site using cookies, you may be asked to fill out a form providing such information as your name and interests.
This information is packaged into a cookie and sent to your Web browser which stores it for later use. The next time you go to the same Web site, your browser will send the cookie to the Web server.
The server can use this information to present you with custom Web pages. So, for example, instead of seeing just a generic welcome page you might see a welcome page with your name on it.

Most sites that provide some form of e-commerce, membership or subscriptions use cookies.

It also allows the sites to retrieve the information stored in the cookie when you return to provide you with a personalized user experience …
Your WordPress login is also stored in a browser cookie, as are the logins of any sites you visit, especially if you tick the ‘remember me’ box commonly found in many login forms …
Most users have no idea that cookies are being stored in their computer, or how long the cookies in their browser are storing the information for. Some websites may also place more than one cookie in your browser.
Cookies help to personalize your experience when you visit websites, but they also have disadvantages and can present security risks.
For instance, cookies can identify your IP address and give the sites you visit information about your purchasing behavior that could be onsold to advertisers. This could leave you open to exploitation not only by marketing companies, but other third-party agents that you may not even know about …
