Content-Length response headers with values larger than 2^32 aren't handled
properly. For instance, for the URL above, the server reports

Content-Length: 4370640896 

but Firefox tries to download 75673600 bytes (which is the actual content length
minus 2^32).

Probably an 32-bit integer overflow.






Reproducible: Always

Steps to Reproduce:
1. Download from
<http://ftp.heanet.ie/pub/fedora/linux/core/2/i386/iso/FC2-i386-DVD.iso>


Actual Results:  
Download starts and claims that 73.9MB will be downloaded.

Expected Results:  
Should display the actual length.
Summary: wrong handling of content-length < 2^32 → wrong handling of content-length > 2^32
