Starting today I'm unable to attach files to emails using my gmail account, when opening in firefox.  I'm using the latest version of firefox (31.0) and have been using it fine for a couple of months.  I click on the attachment button, and the search browser does not open.  Email attachments work fine using safari.  

 I've uninstalling and reinstalling firefox, I've cleared my history, cookies and cache.  I've turned my computer off and back on.
