What email service do you use?

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

Any errors in the error console?

My e-mail service is yahoo

Same problem Yahoo also

my e-mail service is yahoo, too.

I still cant open my attachments

If I can't open my attachments from work associates then I can't use FireFox for anything! What gives? I cannot save them and open them. I can't open JPEG or PDF. Does anybody have some input? How long do I have to wait for FireFox to answer?

i have the same problem, cannot open any attachment yahoo is the email

What exactly happens when you try to open or save the attachment?

Does anything in this article help? What to do if you can't download or save files

I use a web-based Novel Groupwise. Looks like Firefox has no answer to this after months (yet all earlier versions coped!). This makes it now redundant as a browser.
