Here’s some bookmarklets I’ve found quite useful in Mozilla. Copy the javascript lines and paste them to the URL field to use them.
javascript:styles='BODY {margin: auto ! important; max-width: 40em ! important; text-align: justify !important}'; newSS = document.createElement('link'); newSS.rel = 'stylesheet'; newSS.href = 'data:text/css,' + escape(styles); document.documentElement.childNodes[0].appendChild(newSS); void 0
javascript:q=document.getSelection();if(!q){void(q=prompt('IMDB Search',''))};if(q)void(location.href='http://us.imdb.com/Find?'+escape(q))
javascript:styles='A {text-decoration: underline ! important}'; newSS = document.createElement('link'); newSS.rel = 'stylesheet'; newSS.href = 'data:text/css,' + escape(styles); document.documentElement.childNodes[0].appendChild(newSS); void 0
javascript:void(location.href='http://web.archive.org/web/*/'+escape(window.location));
javascript:void(location.href='http://babelfish.altavista.com/translate.dyn?url='+escape(window.location)); javascript:void(location.href='http://www.potatoland.org/cgi-bin/shred.pl?'+escape(window.location.hostname)+escape(window.location.pathname));
javascript:styles='BODY {background-image: none ! important; background-color: grey ! important}'; newSS = document.createElement('link'); newSS.rel = 'stylesheet'; newSS.href = 'data:text/css,' + escape(styles); document.documentElement.childNodes[0].appendChild(newSS); void 0
