No, there is no way to "reject" a change. You can attempt to undo the change by making further changes, but that is up to you to accomplish.

Scenario: Chrome Extension listens on content changes of a specific website.

When the Website adds a DIV with a specific class I want to reject that change and/or add additional content to that DIV.

I did not find a way to achieve this. This is my example code:

var observer = new MutationObserver(function (mutations) {
        mutations.forEach(function (mutation) {
            [].slice.call(mutation.addedNodes).forEach(function (addedNode) {
               StartFilter(addedNode);                    

            });
        });
    });

    observer.observe(document, {
        childList: true,
        subtree:true,
        characterData:true,
        attributes:true        
    });

function StartFilter(newNode) {
   $(newNode).find('.Xx.xJ:Contains("wham")').closest("[jsmodel='XNmfOc']").hide();
}

the content inside "newNode" is hidden but that does not appear to have any effect on the site itself.
