Anyway. You can go as far as modifying the HTML page by overriding CSS rules.
Overrode the font on a page I am using at work because the vendor is apparantly not using their own product and the font is fucking tiny in some places.
You can override elements, dynamically remove with a selector wildcard, DNS blocks or subscribe to blocklists that can do all of it.
