If it makes any difference I am using yahoo mail. When I try to open attachments in my emails, a window pops up asking me - what should Firefox do with this file?. I click on the - do this automatically for all files of this type - and then click on the open with button. The file opens. The next time I try to open an attachment of a similar type the window pops up again instead of the attachment automatically opening. Why is this happening and what do I do to correct it?
