The problem is with mozilla 1.7.2 and happens on 3 different pcs. Two of them with Xp windows without service pack and the other with XP service pack2. Any other function seems to be ok. The download manager shows that finishes the file without problem. I uninstalled the Mazilla browser and reinstalled it with clear install(new profile-new installation path-clear registry files) and it behaves exactly the same. In address bar i used the about:config and turned the max downloads from a server from 2 to 10, but i download one file at the same time, seems not to be the problem. Reproducible: Always Steps to Reproduce: 1. Turn from about:config the max downloads from a server to 10 2. download a pdf file (usually about 1.8 Mb is ok) 3. When download is finished try to open it. Actual Results: The file is corrupted and could not be opened. Expected Results: The file could expected to be OK. ISDN 128K line , ISDN 64K Line and Pstn 56K line was used. From different internet providers, seems this is not provider's hardware fault.

What do you mean with corrupted? Is the file size different (truncated?) or is the size ok, but not the checksum?
