I've been noticing that Firefox tends to lag or become unresponsive on certain JavaScript-heavy websites, especially when handling dynamic input fields or real-time data validation. For example, when processing live input validation using JavaScript, Firefox seems to have a slight delay compared to Chrome, which handles the same script smoothly.
One case where this is noticeable is on websites that use real-time network detection based on mobile number prefixes. Has anyone else experienced similar slowdowns in Firefox when dealing with JavaScript-heavy form validation? Could this be related to Firefox’s rendering engine or specific security restrictions that affect JS execution speed?
