Unfortunately that is not my case: the following short example is the page used
for testing, and it's already validated by W3C Validator.
(For testing, I did cut down a larger file to the minimal parts showing the 
flaw)

The problem seems always related to Firefox opening up to 4 concurrent
connections to remote server, while IE does it sequentially.
Sometimes the concurrent transfers go well, some others they don't, and I miss
incoming parts, like the first data packet to my lwIP server.
