 Just realized this upon comparing it with Safari while investigating a css
 bug.

 In Safari it's nice and snappy. In Camino (and possibly FF), there is 1s
 or more of lag when:

  - TinyMCE is loading in the editor
  - The widgets screen is loading

 It seems related to performance differences between the jQuery selectors
 (dunno about the TinyMCE equivalent) in script engines.

Comment(by Denis-de-Bernardy):

 the one for the admin menu only happens on the widgets script.
