Since last week I cannot attach a file in Yahoo mail using Firefox, but I still can in Chrome. Everything in Firefox is up to date. It's annoying have to switch browsers every time I need to send a file. How can I fix this?

First have you attempted restarting Firefox in Safe mode to see if one of your add-ons maybe conflicting with Yahoo!?
