When users of reddit.com submit a link to a page on reddit.com, that link points to the desktop version of the site. Mobile users have the option of using the newer mobile site (m.reddit.com) or the compact site (i.reddit.com). This addon is specific to the compact site, and ensures links followed to reddit.com from the compact site are opened in the compact mode.
Reddit's new gallery feature is not supported by their compact view, so version 1.5 of Compactify adds a rule so it does not adjust any links going to reddit.com/gallery.
