How can PHP handle browser-specific issues like Firefox not recognizing HTTP_ACCEPT_LANGUAGE in a redirect?

To handle browser-specific issues like Firefox not recognizing HTTP_ACCEPT_LANGUAGE in a redirect, you can check if the browser is Firefox and manually set the language header before redirecting. This ensures that the correct language is passed to Firefox during the redirect process. 

if(isset($_SERVER['HTTP_USER_AGENT']) && strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') !== false) {
    header('Content-Language: en');
}
header('Location: http://example.com');
exit();
