Install software updates so that attackers cannot take advantage of known problems or vulnerabilities. Many browsers like Firefox, Google Chrome and Microsoft Edge offer automatic updates. If this option is available, you should permit it.
Your web browser is your principal connection to the Internet, and multiple applications may rely on your browser, or parts within your browser, to function. Web applications try to improve your browsing, but this might be needless and may leave you vulnerable to being attacked. The best approach is to adopt the highest level of security and only enable features when needed. If you decide that a site is trustworthy, you can choose to enable the feature temporarily and then disable it once you are done visiting the site.
