Google検索だけでいいならこれでどう？
function StraightGoogle(node) {
var lnks = document.evaluate('.//a[@href][@onmousedown]', node, null, 7, null);
for (var i=0; i<lnks.snapshotLength; i++) {
lnks.snapshotItem(i).removeAttribute('onmousedown');
}
}
StraightGoogle(document);
document.addEventListener('AutoPagerize_DOMNodeInserted', function(e){
StraightGoogle(e.target);
}, false);
