User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 20141106120505 Steps to reproduce: send an email and specify the object of communication Actual results: the field "to:" and the filed "object:" are not active. I can only fill the form with the text, I see correctly my email address "from:" but it is not possible select a name from contacts list and describe the object. I previous use the release 24; with this 31 it is th first time I note this kind of problem. Some times in the filed "to:" appears a certian contact from my contact list, as default; but I need to choose the contact !! Expected results: Select again the receiver form the contact list or write a new contact, and write the object of communication with keyboard; as usual

The fields should be fillable when you click on them, no?

No, filed is NOT fillable

Try running in -safe-mode (Help | Restart with Add-ons disabled). I think I recall there's some add-on/theme that can cause that.
