I don't know why I never noticed this, but I just realized that web part
pull-down menus (the menu you select to choose EDIT WEB PART) doesn't
work in Firefox.
Instead, you click the triangle and the page does a post-back, and then
get the editing pane on the right.
So, any 'fixes'/3rd party solutions for this?
At the very least, maybe some custom CSS to swap out the arrow with a
'EDIT' icon for Firefox users?
