Unable to download attachments from my yahoo mail with Firefox or Internet Explorer browser,?

After a month of the same problem starting mid November 2013, I finally fixed this problem on several but not all computers. I went into yahoo mail settings and clicked on the Security and clicked on the option to always use email in "http" and suddenly after a month of misery, the pop up window popped up with the attachments when trying to open them. Interestingly after going back to Security, the option disappears from Security after choosing it. Incidentally, hard to find but this is also an official yahoo answer from yahoo but I fixed it prior to finding that out. They acknowledged the problem.

Have you tried uninstalling internet explorer 11?

Had all my computers and browsers stop doing downloads at one time. Finally found out my bookmark was not correct any more. To fix: Log out, start the mail using a Yahoo! button, log in as usual. Book mark that page. Toss the old one. You will note there is a slight difference in the bookmarks, probably has to do with security, but who knows. Ron

I have a same problem. IT IS VERY FRUSTRATING !!!! I have been forwarding my e-mails with attachments to my gmail account and I was able to open the attachment there. However, today when I forwarded an important mail the attachment is not forwarded with it. Can anyone help with the issue? Thank you!

Same problem. I'm sure it's Yahoo's fault, but can't seem to get their attention.

I have the same problem in Google Chrome

I have same problem on win 8.1 and win 7 using chrome....
