I'm using WordPress 3.2 beta1 + FF4 and the formeditor doesn't work anymore. I can see the contents of the form just fine, but I can't edit any fields.
I can add fields just fine (and only after I tested that I got the Edit & Remove links to show up on hover again) but clicking on Edit doesn't do anything, unless it's a newly added field.
Same with Safari 5.0.5. Both on OSX 10.6 btw.
