Since my striped drive is humongous, I wanted to use it to hold large files such as DVD installation ISO files. Whenever I start a download, it asks for me to put in the path to download to and I choose the drive. It then closes the dialog and doesn't download anything. It doesn't even throw an error message. If I select /home/downloads it works fine. For what it's worth it's a LVM2 striped drive across discs sdb/sdc/sdd/sde.

I've looked through the Firefox troubleshooting guide and it hasn't helped.

Any ideas?
