Ask HN : Freeze that page

Don't you hate it when something steals your focus ? Some websites have become nigh unreadable with all the singing and dancing flash, gifs, auto-play and what not in the margins, popping up left, right and center, vying for you attention and distracting you. Wouldn't be great to have a plug-in that 'freezes' a page so you can actually read its content without all that jazz ? Is there such a thing and if not, what would be a good approach to go about creating one ?
