While being an excellent script, it hasn't been updated in a while and has fallen prey to Google updates. So, it no longer works. Fear not, the fix is quite simple - update it yourself.

I'll even provide the code:
var css = ".vspib, .vspii,vspiic, .vspi {display: none !important;} #vsi, #vsic, #vsrs, #botstuff, #vspb {display: none !important;}";

Save and enjoy.

Just wanted to say thanks. This should hopefully make using Google search tolerable again. =:/

Great Script Buddy
Thank You Very Much
Keep Scripting :)

Working well after the Aug 17 update, hides the preview window and the button completely.

Google changed layouts again mid-September, and now "Cached" and "Similar" links got pushed into the preview window.

Please add this into the css string to return them to their proper location:

.vshid {display:inline; margin-left:7px;}

Thank you! Works perfectly.

Love this script -- thanks very much for your August 17th update. I don't like this annoying google "feature" and your script removes it!

thanks again.

This script only hides the preview buttons, it doesn't actually stop them working, so the issue of accidentally mousing over them still exists. Fix this and I'll give it 5 stars!

// I changed only the style defininitions a little (so they work on Opera) and also the google site detection

var hostnam = top.location.host;
if (hostnam.indexOf("google.com") != -1 ) {
var css = ".vspib, .vspi {display: none !important;} #vspb {display: none !important;}";
if (typeof GM_addStyle != "undefined") {
GM_addStyle(css);
} else if (typeof PRO_addStyle != "undefined") {
PRO_addStyle(css);
} else if (typeof addStyle != "undefined") {
addStyle(css);
} else {
var heads = document.getElementsByTagName("head");
if (heads.length > 0) {
var node = document.createElement("style");
node.type = "text/css";
node.appendChild(document.createTextNode(css));
heads[0].appendChild(node);
}
}
}

Previews still generated with an onclick function within the search snippet. None the less, a big improvement on this new annoying google feature. Thanks.

Works in Opera 11.01 :)
