I would like to install in Internet Explorer 11 the script described in Meta 1043, but am unable to find instructions for doing so. (The article referenced in "For other browsers please read the existing article on stackapps about how to install user scripts." does not address IE.) Any advice would be appreciated. Thanks.
Unfortunately, I don't have a direct solution. It seems that modern user scripts can be run easily on each browser, except of IE. What I found is the following discussion on SO where someone asked the exact same question

Both frameworks seem to target what you have in mind, but I don't know any of them. Since I'm not using IE, even in the few minutes every year that I spend on Windows, I cannot be of further help.
