ReEnableRightClick

To re-enable right click, paste this into the developer console.

function enableContextMenu(aggressive = true) { 
    void(document.ondragstart=null); 
    void(document.onselectstart=null); 
    void(document.onclick=null); 
    void(document.onmousedown=null); 
    void(document.onmouseup=null); 
    void(document.body.oncontextmenu=null); 
    enableRightClickLight(document); 
    if (aggressive) { 
        enableRightClick(document); 
        removeContextMenuOnAll('body'); 
        removeContextMenuOnAll('img'); 
        removeContextMenuOnAll('td'); 
    }
} 
function removeContextMenuOnAll(tagName) { 
    var elements = document.getElementsByTagName(tagName); 
    for (var i = 0; i < elements.length; i++) { 
        enableRightClick(elements[i]); 
        enablePointerEvents(elements[i]); 
    } 
} 
function enableRightClickLight(el) { 
    el || (el = document); 
    el.addEventListener('contextmenu', bringBackDefault, true);

    el.addEventListener('click', bringBackDefault, true); 
    el.addEventListener('mousedown', bringBackDefault, true);
