Downloaded files disappear after download finishes


I downloaded a file from several locations. Mozzila backup, evernote and other downloads

The download finishes, but the file disapears afterwards from my system and can't be found back.

The download should be on the location as requested.

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

See "Disable virus scanning in Firefox preferences - Windows"

If you have that problem in the Download Manager window then reset the browser.download.manager.retention pref to 2 on the about:config page via the right-click context menu.

I have this problem too, I have selected the downloads folder, when the download is finished it disappears, I have done a search of the files, and they simply are no longer on my computer. How do I fix this. I looked at the above articles and all that was suggested was to change the strings, but didn't say what to change the strings too. I have already deleted firefox and then redownloaded it and reinstalled it. How do you fix this?

I have reset everything to default, I have eliminated cleared the database, cleaned the registry, reinstalled and the files still disappear after they are downloaded

I have done the steps here: http://kb.mozillazine.org/about:config

and this one and still nothing: http://kb.mozillazine.org/Unable_to_save_or_download_files

I have this issue to, in Window Vista with FF 18.0.2; if have disabled plug-ins, disable Avast firewall and scanning, reset Firefox to default settings. The only thing I have not done is reinstalled because I cannot download the file. Any thoughts
