Modals are those in page pop-up windows. Those pop up windows aren't their own window or alert window. This tries to remove all of them. Annoyed with pages asking you to sign up with newsletters? Hate it facebook has a big annoying window to ask you to sign in when you just want to look at a post? Tired to being forced to click "agree" in a terms and conditions popup so you can view a page? Me too. Got so tired of it I took time to make this. Please be aware that some pages/web app require modals to function. You can also: Whitelist/ignore list of hosts that you don't want to disable modals on. Set custom domain and patterns list. Turn off automatic removal and disable modals on a per-page basis.
