title: Regex browser search?
body: <p>Is there a way to use the "find" (<kbd>Ctrl</kbd> + <kbd>F</kbd>) function or something similar in a browser, but use a <a href="http://en.wikipedia.org/wiki/Regular_expression" rel="noreferrer">regular expression</a> to search?</p>
  
  <p>I have been looking through add-ons and the such, but I can't find anything to suit my needs. I have found tools to search the HTML source, but that's not as useful.</p>
