3.5 Given a scenario, configure and use web browsers.

📘CompTIA ITF+ (FC0-U61)


Private browsing is a feature available in most modern web browsers (like Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari) that helps users browse the internet without storing certain data locally. It is sometimes called Incognito Mode in Chrome, Private Window in Firefox, or InPrivate in Edge.

The main idea is to increase privacy on the device you are using.


Key Features of Private Browsing

When you use a private browsing session, the browser does the following:

  1. Does Not Store Browsing History
    • The websites you visit in a private session are not added to your browser’s history.
    • This means if someone else opens the browser later, they cannot see the websites you visited during that session.
  2. Does Not Save Cookies Permanently
    • Cookies are small files that store website data, like login sessions or preferences.
    • In private mode, cookies are temporary and are deleted automatically when you close the session.
  3. Does Not Save Form Data or Search History
    • Any information you type into forms, like usernames, search queries, or addresses, is not saved after you close the private window.
  4. Does Not Save Downloaded Files in History
    • Files you download are saved on your computer, but the browser does not remember that you downloaded them.
    • The downloaded files themselves remain accessible in the download folder.

What Private Browsing Does NOT Do

It’s important to understand the limitations for the exam:

  • Does NOT make you anonymous on the internet
    • Your internet service provider (ISP), employer network, or the websites themselves can still track your activity.
  • Does NOT prevent malware or phishing attacks
    • Private mode only affects local data storage. It does not provide extra security against malicious websites.
  • Does NOT hide your IP address
    • If you need to hide your IP, you would need a VPN or proxy in addition to private browsing.

How Private Browsing is Used in IT Environments

In IT-focused scenarios, private browsing is useful for:

  1. Testing Websites
    • IT staff or developers can open a site in private mode to test how it behaves without cached data or stored cookies affecting the session.
  2. Multiple Logins
    • Users can log into a website with different accounts in separate private sessions without logging out of their main browser account.
  3. Avoiding Cached Data Conflicts
    • When troubleshooting websites, private browsing ensures that old cache files do not interfere with viewing the current content.
  4. Temporary Use on Shared Computers
    • Employees can browse sensitive company information on a shared machine without leaving traces in the browser for the next user.

Exam Tips for Private Browsing

  1. Remember the core features: no history, no cookies saved permanently, no form data saved.
  2. Know the limitations: does not hide your IP, does not encrypt traffic, does not prevent malware.
  3. Know why IT professionals use it: testing, multiple logins, troubleshooting, temporary private sessions.
  4. Private browsing is often a quick, local privacy solution but is not a full security solution.
