Any "well-behaved" app on the Mac will let you type ⌘+? to open the help menu search box. However Firefox overrides this behavior. Instead of opening the help search box in the menu bar, it opens a page on Firefox's website. I find this extremely annoying. Is there an about:config entry I can add or edit, or some other way, to get the default behavior for ⌘+?
Using Mac OS X 10.6.4, Firefox 3.6.10
