Everytime I download a file other than a pdf, it gets automatically deleted when finished downloading.

I am using Firefox 7.0.1. Shortly after a Firefox update, I noticed that every time I download any type of file except for .pdf files, they automatically get deleted as soon as they finish.

I tried downloading to my c: drive, a flash drive even a CD with the same result. Why does this happen? I also can't open any downloaded attachments I get in e-mails.

I can download files and or e-mail attachments via Internet Explorer with no problems other than it (IE) randomly locks up. I even tried restoring my system to a previous configuration with no luck. Can you help?

You posted this with a computer running a Firefox 7.0.1 according to the system details.

You can find the latest Firefox release in all languages and for all Operating Systems here:


It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox. Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
