I don’t like the pause that occurs at the end of a download in Firefox.  It’s some sort of security or virus scan but it’s annoying.
I have anti-virus installed and running all the time so I don’t need it.  It’s never actually stopped anything anyways.

To turn it off type about:config in the address bar.
Answer yes to the question warning you about messing up your computer.

In the search bar type “browser.download.manager.scanWhenDone”Change the setting to false and there you go.  No more pausing.

Security is such a pain sometimes.
