How to disable FireFox’s built in antivirus scanning

In Windows Firefox automatically uses the local virus scanner, if installed, to scan any file it downloads. While this may provide extra safety, the real-time scanning functions of modern antivirus programs render this additional scanning unnecessary and causes delays, false positives and even freezes when downloading files – especially large ones.

To disable Firefox's automatic virus scanning perform the following steps:

  1. In the address bar type about:config
  2. In the filter bar (CTRL+F) type browser.download.manager.scanWhenDone
  3. Double click this entry to toggle it from the default true to false
  4. Close all open Firefox windows and restart to apply the change

Disable .DS_Store files on network shares

Apple's Mac OS X automatically creates a hidden file called .DS_store on any file system it encounters, including SMB (Windows) networks, similar to Windows' desktop.ini file.

To prevent its creation on network shares, follow these steps on the Apple computer:

  1. Open Terminal (/Applications/Utilities/Terminal or click the magnifying glass in the top right of the screen and type Terminal)
  2. Execute the following command
    defaults write com.apple.desktopservices DSDontWriteNetworkStores true
  3. Either restart the computer or log out and back in.

To disable .DS_store creation on network drives for all users see Apple's article.
