Both in Firefox 3.6.3 and in Google Chrome, i cannot view "finds/hides by type" from the profile page. In the past, i could click on the "?" icon in the finds column on my profile page, and the result would be a list of *only* mystery caches. Now, any time i click any individual icon on any profile page, the result is a list of *all types* of found or hidden caches.
