Works gloablly accross all the pages. Affects only the URL within gigapedia.com.
Whenever it encounters any link to Gigapedia item pages, it modifies the corresponding
URL to point directly to the download pages of that item, without going to the usual
gigapedia default of first showing the user comments.
