What Does a Web Browser Do?

A web browser is a powerful tool that lets you access the internet, view text, images, videos, and more. Popular browsers include Firefox, Google Chrome, Microsoft Edge, and Apple Safari.

How Has the Internet Changed?

The internet has changed the way we work, play, and interact. It’s bridged nations, driven commerce, nurtured relationships, and driven innovation. It’s the engine of the future, and it’s responsible for all those hilarious memes.


Why is Accessing the Web Important?

It’s vital to understand the tools we use to access the web. With a few clicks, you can:

  • Send an email to someone on the other side of the world
  • Change the way you think about information
  • Get answers to questions you wouldn’t have known to ask
  • Access any app or piece of information in the fastest time possible

It’s amazing what you can do in such a short period of time!

The Translator of the Web

A web browser is like a translator between us and the web. It takes the code that creates web pages, like Hypertext Transfer Protocol (HTTP) images, text, and videos, and makes them understandable to us. HTTP basically sets the rules that determine how images, text, and videos are transferred over the internet. That means we need a way to understand the Hypertext Markup Language (HTML) and Javascript code to navigate the internet. For example, when you view an ExpressVPN review, your browser loads the page.

Why Does Every Site Look Different?

Sadly, browser makers choose to interpret the format in their own way, which means websites can look and function differently depending on the browser you’re using. This creates a lack of consistency that users don’t enjoy. But don’t worry, you can still enjoy the internet regardless of the browser you choose.

What Makes Web Browsers Tick?

Web browsers fetch data from the internet from a connected server. They use a piece of software called a rendering engine to translate the data into text, images, and other data written in Hypertext Markup Language (HTML). Web browsers read this code and create the visual experience you have on the internet. Hyperlinks allow users to follow a path of pages and sites across the web. Each webpage, image, or video has a unique Uniform Resource Locator (URL), also known as a web address. When the browser visits the server, the data at the web address tells the browser what to look for and the HTML tells the browser where to go on the web page.

What’s Behind the Curtain of Web Browsers?

Uniform Resource Locator (URL)

When you type a web page address, like www.allaboutcookies.org, into your browser and click the link, it’s like giving your browser directions to where it wants to go.

Requesting Content from Servers

The servers where the web page content is stored retrieves the content and displays it for you. But what’s actually happening is that your browser is calling a list of requests for content from various resource directories and servers where the content for that page is stored.

Different Sources of Content

The web page you requested might have content from different sources – images might come from one server, text content from another, scripts from another, and ads from yet another server. Your browser retrieves all the data from the server and uses a rendering engine software to translate the web page from HTML code, images, and text.

What is HTTP and HTTPS?

HTTP: The Basics

  • HTTP stands for Hypertext Transfer Protocol and is the primary communication protocol that sets the rules for internet surfing.
  • It is used to translate the code of web pages into the visual elements that we are familiar with.

HTTPS: The Difference

  • HTTPS is very similar to HTTP, but with one key difference: it encrypts the data that is transmitted from a web page to the user and vice versa.
  • This secure connection is enabled through Secure Sockets Layer (SSL) and Transport Layer Security (TLS) technology.
  • Browsers that use HTTP are able to receive and send data to web pages, while browsers that use HTTPS are able to securely receive and send data to web pages with an encrypted connection.

Exploring the Features of Web Browsers

Important Controls

Web browsers have some important controls that make your web experience a breeze. These include:

  • Address bar: Located at the top of the browser, this is where you type in the URL of the website you want to access.
  • Add-ons and extensions: App developers create add-ons and extensions to help enhance your web experience. These include focus timers, web clippers, social media schedulers, and bookmarks.
  • Bookmarks: If you want to quickly pull up a website you’ve visited previously, bookmark it so you can easily navigate to it in the future without having to type in the URL.
  • Browser history: Your browser history records the websites you’ve visited within a certain time period. This can be beneficial if you need to find information you’ve seen before. We recommend clearing your history if you share your computer with others.

Browser Window

The browser window is the main feature of a browser. It lets you view the content of a web page.


Cookies are text files that store information and data that a particular website can share. Cookies can be helpful for saving your login info and shopping cart, but there is a privacy concern.

Home Button

Your home page is the page you’ve set as your default. It acts as a starting point to launch your web browser and usually includes links to your favorite sites. To easily navigate to your homepage at any time, just click the browser’s home button.

Navigation Buttons

Browser navigation buttons let you go back and forth, refresh or reload a page, and bookmark a page (usually with a star or bookmark symbol).

Browser Extensions

Browser extensions are usually represented by a puzzle piece or three stacked dots or bars. They help you open a new web page by clicking a link, and a new page opens in a tab, allowing you to easily switch between different web pages.

What are Cookies and How do Browsers Use Them?

What are Cookies?

Cookies are digital files that help websites personalize your web experience. They allow a site to remember information you’ve shared, like login info, items in your shopping cart, and your IP address.

Privacy Laws and Cookies

The European Union’s General Data Protection Regulation (GDPR) requires websites to ask permission before using cookies. We recommend considering the cookie request and only accepting the best ones to avoid accepting third-party tracking cookies.

  • Use a private browsing window.

Keeping Your Privacy Private

What is Private Browsing?

Private browsing is a setting that exists in nearly all major browsers to help hide your browsing history from other people using the same computer. People think that private browsing, also known as incognito mode, will hide their identity and browsing history from their internet service providers, governments, and advertisers.

How Can I Clear My History?

Clearing your browsing history is a great way to help keep your sensitive personal information safe. If you’re using a public computer, it’s especially important to clear your history. Here’s how to do it:

  • Firefox: Download Firefox and check out the Firefox Privacy Notice. Firefox helps you stay private online by letting you block trackers and other things that follow you around the web.
  • Chrome: Open Chrome and click on the three dots in the top right corner. Then, click on Settings and scroll down to Privacy and Security. Click on Clear Browsing Data and select the data you want to delete.

How Can I Update My Browser Privacy Settings?

Google Chrome

Updating your privacy settings in Google Chrome is easy:

  • Right-click on your browser and select the three dots
  • Choose the ‘Settings’ drop-down menu
  • Select ‘Privacy and Security’
  • We recommend going to the ‘Clear Browsing Data’ option to delete your browser history, clear cookies and cache
  • Under ‘Cookies and Site Data’, you can tell Chrome to block third-party cookies, block all cookies or allow all cookies
  • You can also tell Chrome to send ‘Do Not Track’ requests when you browse different sites
  • Lastly, choose the level of protection you want Chrome to use when it comes to malicious websites and downloads.

Customizing Your Web Browser
