Legacy Browser: Outdated Web Browsers

A legacy browser is an outdated web browser that is no longer supported by its developer. Common examples include Internet Explorer 10 and below, Firefox Extended Support Releases, and older versions of Chrome and Safari.

What is Legacy Browser?

A legacy browser is an outdated web browser that is no longer actively developed or supported by its original creator. Legacy browsers usually lack support for modern web standards, security updates, and newer features. This can make them unsafe and incompatible with many modern websites.

Some common examples of legacy browsers include:

• Internet Explorer 10 and earlier versions
• Older versions of Firefox like Firefox Extended Support Releases (ESRs)
• Very old versions of Chrome and Safari that no longer receive updates

Using a legacy browser today poses significant security and compatibility risks. They do not support modern web technologies like HTML5, CSS3 and JavaScript ES6. Websites and web apps designed for modern standards may not display or function properly. There are also no security patches for newly discovered vulnerabilities.

Most organizations recommend upgrading from legacy browsers to a modern, actively supported browser like the latest version of Chrome, Firefox, Edge or Safari. These receive regular security updates and can access sites employing the latest web standards. For enterprises, legacy browser usage may require keeping outdated systems andpreventing upgrading to newer tools and platforms. Overall, legacy browsers create technical debt and obstacles to progress.
