javascript:void(location.href='https://web.archive.org/web/*/'+escape(location.href));

Pulls the search query from the current Google results page and reruns it on DuckDuckGo. Edit the last URL in the code to switch to Bing, Brave, or Yahoo.

javascript:Q=[];c=location.search.slice(1).split('&');for(i in c){f=c[i].split('=');if(f[0]=='q'||f[0]=='as_q'||f[0]=='p'||f[0]=='query')if(f[1])Q.push(f[1])}R=unescape(Q.join('; ').replace(/\+/g,' '));location='https://duckduckgo.com/?q='+escape(R);

Search Google limited to the current site's domain. Select text first, or enter a phrase when prompted.

javascript:q=""+(window.getSelection?window.getSelection():document.getSelection?document.getSelection():document.selection.createRange().text);if(!q)q=prompt("Enter a search phrase:","");if(q!=null)location=("https://www.google.com/search?num=100&q=site:"+escape(location.hostname)+" \""+escape(q.replace(/\"/g,""))+"\"").replace(/ /g,"+");void 0

Shows how many pages Google has indexed for the current hostname.

javascript:location="https://www.google.com/search?num=100&q=site:"+escape(location.hostname);void 0

Removes a site's oncontextmenu block so you can open the context menu again. More options in our right-click guide.

Loads the Wappalyzer bookmarklet overlay to list CMS, CDN, analytics, and frameworks on the current page.

javascript:(function(){var d=document,e=d.getElementById('wappalyzer-container');if(e!==null){d.body.removeChild(e)}var u='https://www.wappalyzer.com/',c=d.createElement('div'),l=d.createElement('link'),s=d.createElement('script');c.setAttribute('id','wappalyzer-container');l.setAttribute('rel','stylesheet');l.setAttribute('href',u+'css/bookmarklet.css');d.head.appendChild(l);s.setAttribute('src',u+'bookmarklet/wappalyzer.js');s.onload=function(){window.wappalyzer=new Wappalyzer();s=d.createElement('script');s.setAttribute('src',u+'bookmarklet/apps.js');s.onload=function(){s=d.createElement('script');s.setAttribute('src',u+'bookmarklet/driver.js');c.appendChild(s)};c.appendChild(s)};c.appendChild(s);d.body.appendChild(c)})();

Opens BugMeNot for the current domain to find shared logins for registration walls. Use only on sites whose terms you accept.

javascript:(function(){var url='https://bugmenot.com/view/'+escape(location.hostname);w=open(url,'w','location=no,status=yes,menubar=no,scrollbars=yes,resizable=yes,width=500,height=400');if(w){setTimeout('w.focus()',1000)}else{location=url}})();

Sends the current page URL to Web2PDFConvert. Pages behind a login wall usually fail.

javascript:void(window.open('https://www.web2pdfconvert.com#'+location.href))

Opens a QR code for the current page. Uses QuickChart because Google's old Chart API QR endpoint was shut down. You can also use our QR generator tool.

javascript:(function(){var u='https://quickchart.io/qr?text='+encodeURIComponent(location.href);w=open(u,'w','location=no,status=yes,menubar=no,scrollbars=no,resizable=yes,width=500,height=500');if(w){setTimeout('w.focus()',1000)}else{location=u}})();

Strips event handlers that block selecting and copying text on restrictive pages.

javascript:(function(){function R(a){ona="on"+a;if(window.addEventListener)window.addEventListener(a,function(e){for(var n=e.originalTarget;n;n=n.parentNode)n[ona]=null},true);window[ona]=null;document[ona]=null;if(document.body)document.body[ona]=null}R("click");R("mousedown");R("mouseup");R("selectstart")})()

Shows values stored in password fields on the current page. Only run on pages you trust.

javascript:(function(){var s,F,j,f,i;s="";F=document.forms;for(j=0;j<F.length;++j){f=F[j];for(i=0;i<f.length;++i){if(f[i].type.toLowerCase()=="password")s+=f[i].value+"\n"}}if(s)alert("Passwords in forms on this page:\n\n"+s);else alert("There are no passwords in forms on this page.")})();

Adds sort links to every HTML table on the page. Try it on the W3Schools table demo.

javascript:function toArray(c){var a,k;a=new Array;for(k=0;k<c.length;++k)a[k]=c[k];return a}function insAtTop(par,child){if(par.childNodes.length)par.insertBefore(child,par.childNodes[0]);else par.appendChild(child)}function countCols(tab){var nCols,i;nCols=0;for(i=0;i<tab.rows.length;++i)if(tab.rows[i].cells.length>nCols)nCols=tab.rows[i].cells.length;return nCols}function makeHeaderLink(tableNo,colNo,ord){var link;link=document.createElement('a');link.href='javascript:sortTable('+tableNo+','+colNo+','+ord+');';link.appendChild(document.createTextNode((ord>0)?'a':'d'));return link}function makeHeader(tableNo,nCols){var header,headerCell,i;header=document.createElement('tr');for(i=0;i<nCols;++i){headerCell=document.createElement('td');headerCell.appendChild(makeHeaderLink(tableNo,i,1));headerCell.appendChild(document.createTextNode('/'));headerCell.appendChild(makeHeaderLink(tableNo,i,-1));header.appendChild(headerCell)}return header}g_tables=toArray(document.getElementsByTagName('table'));if(!g_tables.length)alert("This page doesn't contain any tables.");(function(){var j,thead;for(j=0;j<g_tables.length;++j){thead=g_tables[j].createTHead();insAtTop(thead,makeHeader(j,countCols(g_tables[j])))}})();function compareRows(a,b){if(a.sortKey==b.sortKey)return 0;return(a.sortKey<b.sortKey)?g_order:-g_order}function sortTable(tableNo,colNo,ord){var table,rows,nR,bs,i,j,temp;g_order=ord;g_colNo=colNo;table=g_tables[tableNo];rows=new Array();nR=0;bs=table.tBodies;for(i=0;i<bs.length;++i)for(j=0;j<bs[i].rows.length;++j){rows[nR]=bs[i].rows[j];temp=rows[nR].cells[g_colNo];if(temp)rows[nR].sortKey=temp.innerHTML;else rows[nR].sortKey="";++nR}rows.sort(compareRows);for(i=0;i<rows.length;++i)insAtTop(table.tBodies[0],rows[i])}

Turns the page into a temporary editable document. Reload to undo. Handy for mockups, not for publishing.

javascript:document.body.contentEditable='true';document.designMode='on';void 0

Install the bookmarklet from Typewolf's Type Sample page. The old typesample.com script URL no longer loads reliably. Hover over text to identify the font family in use.

Counts single-word frequency across the visible page and opens a sorted list in a new window. Pairs well with our word counter tool.

javascript:(function(){var T={},W=[],C=0,s,i;function F(n){var i,x,a,w,t=n.tagName;if(n.nodeType==3){a=n.data.toLowerCase().split(/[\s\(\)\:\,\.;<>&'"]/);for(i in a)if(w=a[i]){w=" "+w;T[w]=T[w]?T[w]+1:1;++C}}if(t!="SCRIPT"&&t!="STYLE")for(i=0;x=n.childNodes[i];++i)F(x)}F(document);for(i in T)W.push([T[i],i]);W.sort(function(a,b){var x=b[0]-a[0];return x?x:((b[1]<a[1])?1:-1)});s="<h3>"+C+" words</h3>";for(i in W)s+=W[i][0]+":"+W[i][1]+"<br>";with(open().document){write(s);close()}})()

Outlines images in red (missing alt), gray (empty alt), or green (alt present). Hover for the alt text value.

javascript:(function(){function d(s){return s==null?"missing":"\""+s+"\""}var c=[0,0,0],i,P,a,y,D=document;for(i=0;P=D.images[i];++i){a=P.getAttribute("alt");y=!!a+(a!=null);++c[y];P.style.border="2px "+["dotted red","dashed #888","solid green"][y];P.title="Alt: "+d(a)+", Title: "+d(P.getAttribute("title"))}top.status="Image alt texts: "+c[0]+" missing, "+c[1]+" empty, "+c[2]+" present"})()

Checks whether the current host is down globally or only on your connection.

javascript:location='https://downforeveryoneorjustme.com/'+location.hostname

Replaces link anchor text with the full destination URL. Useful on download pages littered with ad buttons.

javascript:(function(){var i,c,x,h;for(i=0;x=document.links[i];++i){h=x.href;x.title+=" "+x.innerHTML;while(c=x.firstChild)x.removeChild(c);x.appendChild(document.createTextNode(h))}})()

Loads the performance-bookmarklet overlay with Navigation Timing and Resource Timing data. Some sites block it with Content Security Policy.

javascript:(function(){var el=document.createElement('script');el.type='text/javascript';el.src='https://micmro.github.io/performance-bookmarklet/dist/performanceBookmarklet.min.js';el.onerror=function(){alert("CSP blocked this bookmarklet. Paste the script URL into the browser console instead.");console.log("https://micmro.github.io/performance-bookmarklet/dist/performanceBookmarklet.min.js")};document.getElementsByTagName('body')[0].appendChild(el)})();

On a Google Play app page, opens APKMirror search for that package ID. Not every app is listed there.

javascript:var regeX=/[?&]id=([^&\n]+)/,match=location.href.match(regeX);if(match){var url="https://www.apkmirror.com/?s="+escape(match[1])+"&post_type=app_release&searchtype=apk";(w=open(url,"w","location=no,status=yes,menubar=no,scrollbars=yes,resizable=yes,width=500,height=800"))?setTimeout("w.focus()",1000):location=url}else alert("Open a Google Play app page first, e.g. play.google.com/store/apps/details?id=...");
