On extension click, any element with 'position: fixed' is removed from the page.
I grew tired of news websites cluttering up the page with frozen headers and share buttons.

Fixed bars like this infest sooo many websites, cluttering the view and restricting how much of the content you can see at once, and ad blockers usually don't remove them. This extension lets you get rid of them quickly. Minor issue: I have to click the toolbar button twice before it works.
