Is it really that hard to find? I mean it's still a little bug and the
colors are similar.
Of course it can be irretating at the beginning, that the icon
changed. Therefore the wiki and feature pages have to be updated
together with the 1.6 release. Though this is more compliant to the
new logo at
getfirebug.com and in my eyes also a more professional and
modern icon.
@John: Are you able to change the Firebug logo here at the Google
pages, too?
