My website is experiencing compatibility issues with certain browsers, such as Firefox. I want to display a message when users visit the webpage using an unsupported browser, similar to how http://species-in-pieces.com shows a notification saying "Works Best in Chrome. You Can Download it Here." for non-Chrome users. I need a message to appear specifically for Firefox and other unsupported browsers (e.g. gaming console browsers), but it should also have an option to dismiss or ignore it since many of my users use those browsers. Any suggestions are welcome, thank you!
