Hello,

"Tools -> Internet Options -> Advanced

When in the Advanced tab, did these two things
1) Click "Restore Advanced Settings"
and than
2) Click Reset (and OK to all the message warnings)
'
After I did that, I was able to upload e-mail attachments on g-mail with Firefox, Chrome, and Internet Explorer."
