How to disable Back button in IE and firefox? [duplicate]

Answer 1

The answer is "no". You cannot disable a browser's back button.

Or at least on a good browser.

Answer 2

I believe this question has already been asked:

Disabling Back button on the browser Prevent Use of the Back Button (in IE)

If you're trying to prevent the user from losing their work, try something like:

window.onbeforeunload = function() { return "You work will be lost."; };

Answer 3

I would argue you should not disable the back button it at all possible as users are used to using it and it will frustrate them to find its functionality removed.

The users flow will be interrupted and they will leave your site.

Answer 4

There is no solution for that problem. You can't really "disable" it.
