Understanding Browser Basics and What They Do

A web browser is software that lets you view websites and interact with content online. When you type a web address into your browser or click a link, the browser sends a request to a web server, which sends back the website's code. Your browser then reads that code and displays the website on your screen. Common browsers include Chrome, Firefox, Safari, and Edge. Each browser works slightly differently, which is why a website might look or function differently depending on which one you use.

Browsers have been around since the 1990s, and they've changed significantly over time. The first browser, called WorldWideWeb, was created by Tim Berners-Lee in 1989 and could only display text. Today's browsers are sophisticated programs that handle images, videos, interactive elements, and complex applications. According to recent data, Chrome holds about 65% of the global browser market share, followed by Safari at 20%, Firefox at 4%, and Edge at 4%, with other browsers making up the remaining 7%.

When you visit a website, your browser needs to handle multiple tasks at once. It retrieves images, loads style sheets that control how things look, runs JavaScript code that makes things interactive, and manages security features to protect your information. Modern browsers are designed to do all this smoothly and quickly, but older browsers or browsers on older devices might struggle with complex websites.

Understanding what a browser does helps explain why website owners care about which browsers people use to visit their sites. If you're having trouble viewing a website, it might be because your browser is outdated or doesn't support certain features. Knowing the basics about how browsers work can help you troubleshoot problems or understand why a website might not look right on your device.

Practical takeaway: Your browser is the tool that translates website code into what you see on screen. Different browsers can display the same website differently, and older browsers may not support newer website features. If a website isn't working properly, trying a different or updated browser might solve the problem.

How to Check Your Current Browser Version

Knowing which browser you're using and what version it is matters because websites are built to work with specific browser versions. A browser version number tells you how current your browser is. For example, Chrome version 120 is much newer than Chrome version 90. Website developers test their sites with different browser versions to make sure they work properly. If your browser is very old, a website might not function correctly.

Checking your browser version is straightforward. In Chrome, click the three vertical dots in the upper right corner, then click "About Google Chrome." The browser will automatically check for updates and show you your current version number. In Firefox, click the hamburger menu (three horizontal lines) in the upper right, select "Help," then "About Firefox." In Safari, click "Safari" in the menu bar at the top of your screen, then select "About Safari." In Microsoft Edge, click the three dots in the upper right, select "Help and feedback," then "About Microsoft Edge."

When you check your browser version, you'll see a version number that typically looks like this: "Version 120.0.6099.129." These numbers represent the major version, minor version, and build number. The first number is most important for understanding how current your browser is. Most modern websites work best with versions from the last two to three years, though many websites are designed to work with browsers going back five to seven years.

Browser developers release new versions regularly. Chrome, Firefox, and Edge release major updates every four weeks. Safari updates with iOS and macOS releases, typically several times per year. These updates include security patches, bug fixes, and support for new web technologies. When your browser notifies you that updates are available, installing them keeps your browser compatible with modern websites and protects your security.

Practical takeaway: Check your browser version through your browser's menu. Most browsers make this easy by going to Help or About sections. If your version number is more than a year old, updating your browser could improve how websites look and function for you.

Minimum Browser Requirements Websites May Have

Many websites have minimum browser requirements, which means they need a certain browser or browser version to work properly. These requirements exist because different browsers support different technologies. A website built using advanced features might not work on an older browser that doesn't support those features. For example, if a website uses WebGL (a technology that allows 3D graphics in browsers), it won't display those graphics in browsers that don't support WebGL.

Common minimum requirements include specific browser versions, operating system compatibility, and support for certain technologies like JavaScript, HTML5, or CSS3. A website might state that it requires Chrome 100 or higher, Firefox 98 or higher, Safari 15 or higher, and Edge 100 or higher. Some websites specify that they work best on Windows, macOS, iOS, or Android. A few websites still have requirements for Internet Explorer, though this browser is no longer supported by Microsoft as of June 2022.

Banking and financial websites often have strict browser requirements because security is critical. Many banks now require modern browsers with strong security features and no longer support Internet Explorer. Government websites also frequently specify browser requirements. For example, the Social Security Administration recommends using modern versions of Chrome, Firefox, Safari, or Edge. Educational websites, healthcare portals, and corporate systems may all have specific requirements.

If you try to visit a website that has minimum requirements you don't meet, you might see an error message, or the website might not display or function correctly. Some websites automatically detect your browser and show you a message recommending an update. Others display incorrectly without warning you why. If you encounter problems visiting a website, checking if your browser meets the minimum requirements is a useful troubleshooting step.

Practical takeaway: Websites may require specific browser versions because they use modern technologies. If a website doesn't work for you, look for a requirements page or help section. Most official websites list their browser requirements, and updating your browser often solves compatibility problems.

JavaScript, Cookies, and Other Browser Features You May Need

Beyond just having the right browser version, websites often need specific features to be turned on in your browser settings. JavaScript is the most common of these features. JavaScript is a programming language that makes websites interactive. It powers things like dropdown menus, form validation, auto-saving features, and dynamic content that changes without reloading the page. According to recent web statistics, approximately 98% of all websites use JavaScript. If JavaScript is disabled in your browser, most modern websites won't work properly.

Cookies are small files that websites store on your device to remember information about you. When you visit a website, it might store a cookie that remembers your language preference, shopping cart items, or login information. Some websites won't function without cookies turned on. For example, if cookies are disabled, you might not be able to stay logged into your email account while browsing, or a shopping cart might not remember items you added. Cookies are often misunderstood—they're not viruses or spyware, though some people disable them for privacy reasons.

Other browser features that websites may require include: local storage (which allows websites to store larger amounts of data on your device), pop-up support (for websites that open new windows), WebGL (for 3D graphics), and geolocation (which allows websites to know your general location). Most modern browsers have these features turned on by default. Some people disable JavaScript or cookies intentionally for privacy or security reasons, but doing so may cause websites to malfunction.

If a website isn't working properly and you've confirmed your browser is up to date, checking your settings might help. To enable JavaScript in Chrome, go to Settings, then Privacy and Security, then Site Settings, then JavaScript, and make sure it's toggled on. Similar steps work for other browsers. If you're unsure whether a website requires cookies or JavaScript, most websites have a help or FAQ section that explains their requirements.

Practical takeaway: Most websites need JavaScript enabled and accept cookies to function properly. These features are usually on by default in modern browsers. If a website isn't working, checking that JavaScript and cookies are enabled in your browser settings might solve the problem.

Screen Size, Operating System, and Device Compatibility

Website requirements aren't just about browser versions—they also include the device you're using. The same website may work differently on a desktop computer with a large screen than on a smartphone with a small screen. Website designers create responsive designs that adjust to different screen sizes, but some websites are built primarily for desktop computers and may not work
