Which browser is not supported by the Okta Browser Plugin?

The correct answer is Internet Explorer 11, as it is not supported by the Okta Browser Plugin. This plugin is designed to enhance security and user experience while using web applications. However, Internet Explorer 11 is an older browser that does not receive regular updates or support from Microsoft anymore, which can lead to compatibility issues, security vulnerabilities, and an overall lack of functionality when compared to more modern browsers.

By contrast, Microsoft Edge, Google Chrome, and Mozilla Firefox are contemporary browsers that are actively maintained and updated, allowing the Okta Browser Plugin to work effectively within those environments. The support for these browsers ensures that users can take advantage of the latest security features and web standards, which are integral to a seamless experience with applications that utilize Okta for authentication.
