Works great for searching normally and with regex. However, it hijacks the word "find" with NO option to disable it, which I do not like. Search hijacking is something trashy malware does and if its a feature it should be optional.

It's good for regex search.

But for some reason, this add-on takes over whenever you use the search bar for anything beginning with 'find'. You can only use it to see how many matches are on the page. Annoying and useless feature.

this is too buggy and slow. use a bookmarklet instaed. make a new bookmark call it whatever you want and add as link: "javascript:(function(){var count=0, text, regexp;text=prompt("Search regexp:", "");if(text==null || text.length==0)return;try{regexp=new RegExp("(" + text +")", "i");}catch(er){alert("Unable to create regular expression using text '"+text+"'.\n\n"+er);return;}function searchWithinNode(node, re){var pos, skip, spannode, middlebit, endbit, middleclone;skip=0;if( node.nodeType==3 ){pos=node.data.search(re);if(pos>=0){spannode=document.createElement("SPAN");spannode.style.backgroundColor="yellow";middlebit=node.splitText(pos);endbit=middlebit.splitText(RegExp.$1.length);middleclone=middlebit.cloneNode(true);spannode.appendChild(middleclone);middlebit.parentNode.replaceChild(spannode,middlebit);++count;skip=1;}}else if( node.nodeType==1 && node.childNodes && node.tagName.toUpperCase()!="SCRIPT" && node.tagName.toUpperCase!="STYLE"){for (var child=0; child < node.childNodes.length; ++child){child=child+searchWithinNode(node.childNodes[child], re);}}return skip;}window.status="Searching for "+regexp+"...";searchWithinNode(document.body, regexp);window.status="Found "+count+" match"+(count==1?"":"es")+" for "+regexp+".";})();" without the first and last ""

Is there a way to make this automatically highlight certain values on a particular page every time it loads with 0 input from the user?

not great yet, no kbd shortcuts, no focus on edit box when triggered, no scrollbar highlight, no search text persistence.. ff integrated search much better.

Works OK for me ff 5.2 64 bit
