Prevent alert boxes from appearing in Firefox

Question

Question by Trevor Roberts

I can use this in my Opera browser to stop the alert boxes from appearing:

javascript:function alert () {}

However, it does not work whenever I use this in Firefox. What is the command to stop the alerts in Firefox?

Answer 1

This can be done like this

window.alert = function() { return false; }

But, if you want to stop the alert boxes, best solution is not to use alert() at all.
Disabling the JavaScript functions in not right solution.
