In Mobile me, when I go to add an attachment to an e-mail (nothing fancy just an excel, word, *.pdf or *.jpg small file) I can select the file but when I select 'open' it doesn't attach the file. I get no error message. I talked with Apple and I cleared everything for cookies and cache but it did not fix the problem. This does not happen in Safari. However, I prefer to use Firefox.

This just started a few weeks ago and may have been when I upgraded to Firefox 7.0.1
