Again, downloading files does not work. But this time, it's more serious: When following an url that
points to a file, the browser crashes. Thus downloads are impossible.

The problem arises with the newest version of firefox: 47.0. Regretfully, the behavior is the same when
replacing firefox with palemoon. Otherwise, I use archlinux and conkeror-git 160130.1.20.g9f2b548-1.
There is no message in the console.

Any help would definitely be appreciated.
