A browser is an application software that allows you to access web pages when using the Internet. The most popular browsers today include Google Chrome, Safari, Firefox, and Internet Explorer, with Google Chrome being the most widely used and rated as the fastest, safest, and most convenient browser.

To know information about your browser and its settings, you can use free tools like What is my Browser, available on DHL Seo Tool. This tool allows you to identify the browser name, version, operating system, user agent, cookies, and JavaScript you are using. Understanding this information will help you decide whether or not you need to update your browser.

If you are a web developer, understanding your customers' browsers will help you optimize your website to work well on many different browsers. The What is my Browser tool is also very useful for internet cafes and people who are new to accessing the internet.
