finding the right scope, and exchange line in site script

Greetings!

I'd like to get rid of an anti-adblocker script on weather site www.kachelmann.com. The script is called function.js, and the function in question goes like this:

.
.
.

$(document).ready(function () {
.
.
.
    if ($('#paywall-account-type').attr('data-value') !== 'payaccount') {
        try {
            nx.cmd.push(function () {
                nx.trigger('rescan');
            });
        } catch(err) {};

        a457c035a6dd2ca7c69(function(ret, triggerText) {
            var adblocker = 'Unknown';

            if(ret) {
                adblocker = 'Enabled';
                var infocounter=0;
                $('.md').each(function() {
                    infocounter++;
                    $(this).css('background-color','#f7284b');
                    $(this).css('color','#ffffff');
                    $(this).css('height','100%');
                    $(this).css('font-size','13px');
                    $(this).removeAttr("data-nx-container");
                    if (!isGoogle()) {
                        $(this).html(adblock_txt);
                    }
                    else {
                        $(this).html(adblock_txt2);
                    }
                    if (infocounter>=2) {
                        return false;
                    }
                });
            }
            else {
                adblocker = 'Disabled';
            }
}
.
.
.

So the only thing necessary would be to either change

if ($('#paywall-account-type').attr('data-value') !== 'payaccount') { into if ($('#paywall-account-type').attr('data-value') === 'payaccount') {

or even

adblocker = 'Enabled'; into adblocker = 'Disabled';

The latter - change the value of variable adblocker - works splendidly in the Debugger, the page gets loaded.

So my questions are: How do I open, change and save the file function.js in greasemonkey or any other script loader under Firefox? How do I actually change the variable?

My background is in programming, just not web programming and javascript. By asking you, I am hoping to get by the overhead of having to learn an entire paradigm and programming language just to solve this penny and dime stuff.

Thanks for reading and helping, Schoepke
