javascript:loadScript("http://latex.mathoverflow.net/jsMath/jsMath.js");setTimeout('jsMath.Setup.Script("plugins/tex2math.js");jsMath.ConvertTeX();jsMath.Process(document);',200);void(0);
Now any time you want to render the math on a page, you should be able to do it by clicking the bookmark. If you have to click it twice for it to work, try changing the number 200 to something larger, like 500.
