I have to use a 3rd party website, that only runs fine in the Internet Explorer.
But I still need to edit the HTML of some of the pages by using the F12 Developer Tools. Otherwise it would be very uncomfortable to use them.
How can I apply this changes - or HTML changes in general - every time I visit this pages? A local HTML file is not an option, because the page loads content from the server and the server will not allow access from external domains.
