I've been using this Kill Sticky bookmarklet, and it's turned out to be one of life's simple pleasures. Gets rid of menu bars and popovers. It's the most-used thing on my bookmarks toolbar by a factor of about eleventy babillion. It's not automatic like an extension would be, but you'll find you get 80% of what you want with a tiny bookmarklet. https://alisdair.mcdiarmid.org/kill-sticky-headers/ https://alisdair.mcdiarmid.org/kill-sticky-headers/
