User reviews
I discovered this plugin as a helper for the Infy Scroll extension. Infy Scroll is useful but a little tricky to configure if you want to force Infinite Scrolling on certain sites; a simpler alternative though slightly less powerful is the UserScript Pagetual.

Works for me and nothing bad in the source code, basically removes "content-security-policy" and "x-frame-options" from headers. Thanks!
