Y!Mail AdsFree

UserCSS to remove all advertisement panels and utilize their made available space, whenever possible, to expand existing panels.

IMPORTANT:
a) This extension applies to the NEW version of Yahoo! Mail.
b) UserJS must be activated (or else browser sniffing will disallow page opening) at opera:config#UserPrefs|BrowserJavaScript. Value must be set to "2".
c) If there is some slowness to load the pages from requests to "*us.bc.yahoo.com*", include this address in Opera's built-in Content Blocker while inside Yahoo! Mail.
