Bug 1343718 - Don't display download progress when we don't know the download size in advance. r=chmanchester

Browse Source 
In most cases, the HTTP response for the download will contain the
content-length, but if some error happens (e.g. authentication error),
there might not be one, and the download fails with a TypeError for a
division by None, instead of failing with a more friendly error message
about the HTTP error.
