Thanks, closing then. There might still be a bug though if userContent.css got in a buggy state unless you manually edited it? Anyway that's more of an upstream question and can be discussed on their bugzilla if needed

However, the view of the PDF file only uses about 2/3rds of the screen width, and leaves a large empty grey area on the right hand side of the screen. Zooming in on the document only zooms within the existing area, and does not expand to the grey area.
