it's a quite simple js code i found by accident on a js tutorial website.. it should work on all browsers i think not just gecko. it was injected directly within the macro. yes..your results will be saved if you select save page..all the changes you've made will be included in the saved page. i think it's most handy when trying to redesign your pown html pages directly into the browser just to see how things will look like as a preview before making actual changes in the html code..can also be handy for printing, if you want to exclude some images or replace them with other images or even correct spellings on the page and ofcourse you can just use it for pure entertainment
