A message on my yahoo.ca email says that I am using an unsupported browser. I clicked on the update browser part of that message (orange colour) and followed instructions. Whenever I had to drag anything the whole box got moved and then when I let go the whole box containing what I was to drag literally flew back where it originally came from. The only thing that I was able to do was to put the firefox symbol on my desktop. My first e-mail address was connected to safari, so when I try to print anything that comes up on my e-mail, I cannot print the printable version because "I am using and unsupupported browser." Also I cannot send attachments to yahoo e-mails. I have a gmail address also and send photos and attachments from this address without any problem.
