Comment 9 for bug 85644

For some reason or recent change, links in Update Manager now defaults to the epiphany browser regardless of which browser is set in System|Preferences|Preferred Applications.

$ cat ~/.gconf/desktop/gnome/applications/browser/%gconf.xml
<?xml version="1.0"?>
<gconf>
 <entry name="exec" mtime="1275415696" type="string">
  <stringvalue>seamonkey2</stringvalue>
 </entry>
 <entry name="nremote" mtime="1275415696" type="bool" value="true"/>

Same occurs even if the full path to the browser is provided, and if Firefox is set as preferred.
