Comment 6 for bug 285080

This effects me on a fresh install of Xubuntu 14.04 LTS. Installed about two weeks ago.

I am suddenly unable to download files. I have been blocked downloading a .pdf and a .zip.

Firefox gives me this error message:

"
There is not enough room on the disc to save /tmp/<filename>

Remove unnecessary files from the disc and try again, or try saving in a different location.
"

Thunar tells me my temp folder has 3.1kb space free. It has two folders in it of 1kb a-piece.

My home directory - where I was attempting to download - has 124Gb free.

I installed using the guided / partition wizard. If the partitions under my bonnet are full up already, it suggests to me a very serious problem with the install.

I had 8Gb in trash. Removed that. Problem unresolved.

Since having my computer on today I've done some browsing, opened a lot of tabs, briefly skimmed/skipped some streaming video, displayed some .pdfs in browser.

I'm using Firefox 29.

here's the output of df:
