In what ways can browser-specific issues, such as those in Firefox, impact PHP form functionality?

Browser-specific issues in Firefox can impact PHP form functionality if the browser does not handle form submissions correctly. One common issue is Firefox not sending form data in the expected format, leading to errors in processing the form data on the server side. To solve this issue, you can use PHP to check for specific browser headers or user agents and adjust the form processing logic accordingly. 

if (strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') !== false) {
    // Adjust form processing logic for Firefox
    // For example, handle form data in a different way
} else {
    // Normal form processing logic
}
