AlwaysKillSticky av Said Achmiz

On sites/pages where it’s enabled, AlwaysKillSticky finds all elements whose position CSS property has a computed value of either ‘sticky’ or ‘fixed’, and removes those elements.

AlwaysKillSticky can work in blacklist mode (only killing stickies on sites you specify) or whitelist mode (killing stickies except on sites you specify).

AlwaysKillSticky also optionally allows fine-grained control of which sites and pages stickies are killed on (e.g., if you want to kill stickies on all sites on a domain, or if you want to exclude specific paths of a site).
