When I attach a Word document to an email it shows up as "undefined." Then, when the recipient tries to open it, it says it's an octet stream file.

I can attach documents in Safari with the same email provider without a problem.

Hi mjmonck-

Which email provider are you using? There are different solutions possible for different providers. Yahoo is having trouble with attachments, outside of any Firefox issue. I've seen a Google user fix this by manually adding the mail URL to their ad block program- which mistakenly perceived the webmail page as an advertisement.

Hope this helps.
