Highlight in page:
javascript:(function()%7Bconst%20selectedText%20%3D%20getSelection().toString()%3Bconst%20newUrl%20%3D%20new%20URL(location)%3BnewUrl.hash%20%3D%20%60%3A~%3Atext%3D%24%7BencodeURIComponent(selectedText)%7D%60%3Bwindow.open(newUrl)%7D)()
The Printliminator (Makes a page printer-friendly):
javascript:/*THE.PRINTLIMINATOR*/(function(){function%20loadScript(a,b){var%20c=document.createElement('script'),d=document.getElementsByTagName('head')[0],e=!1;c.type='text/javascript',c.src=a,c.onload=c.onreadystatechange=function(){e||this.readyState&&'loaded'!=this.readyState&&'complete'!=this.readyState||(e=!0,b())},d.appendChild(c)}loadScript('//css-tricks.github.io/The-Printliminator/printliminator.min.js',function(){thePrintliminator.init()});})();
Google Translate a page (since V doesn't have translation built in):
javascript:var t=((window.getSelection&&window.getSelection())||(document.getSelection&&document.getSelection())||(document.selection &&document.selection.createRange&&document.selection.createRange().text));var e=(document.charset||document.characterSet);if(t!=''){location.href='http://translate.google.com/translate_t?text='+t+'&hl=en&tbb=1&ie='+e;}else{location.href='http://translate.google.com/translate?u='+escape(location.href)+'&hl=en&tbb=1&ie='+e;};
Skip ad on CoolMathGames.com (It also gets rid of an "Ad-blocker detected" message):
javascript:(function(){removePrerollAndDisplayGame();document.getElementsByClassName("blocker-detected-2")[0].style.display="none";})();
Most of these I found online somewhere, except I wrote the CoolMathGames one myself.
