And also for edit... you can shorten the script somewhat too - just paste the below

jQuery(".wpforo-reply.wpf-action").click(function(){
jQuery("#wpf-form-wrapper").show();
});
jQuery(".wpf-action.wpforo-quote").click(function(){
jQuery("#wpf-form-wrapper").show();
});
jQuery(".wpforo-edit.wpf-action").click(function(){
jQuery("#wpf-form-wrapper").show();
});

If you have a theme that supports additional JS, you can do this without the plugin quoted by @sofy (as I am doing)

Thank you very much @anonymous3542, I only suggest you use a shorter version of the code: 

jQuery(".wpforo-reply.wpf-action, .wpf-action.wpforo-quote, .wpforo-edit.wpf-action").click(function(){
          jQuery("#wpf-form-wrapper").show();
});
