It's working, but it doesn't always keep the names of the downloaded files and it doesn't really intercept downloads - it just pops up a clickable kind of button and allows you to download the file, but you have to cancel your original download. And - unacceptably - it pops up a page on every browser startup asking for donations. I sync extensions, so this happens on my work computer too - but I can't have a page about extreme downloading popping up there, so I must either quit syncing extensions or uninstall. I choose uninstall.
