Same, I can't stand sticky headers, especially on anything involving longform text content. They also make web archiving significantly harder as scrolled screenshots cant be easily stitched together anymore to get the whole page.
What other way is as convenient and available but better?
Printing as PDF doesn't save the content exactly as it's shown in the browser and a plugin I used for a while in the past was pretty unreliable.
Screenshots work on any device with a modern browser and usually I don't want to capture the entire page anyway but just specific interesting parts.
