does the window immediately close when you do this?
do you get a message in the javascript console (tools|web development|javascript
console)?

note to self:
10 Content-Type: application/x-tar
11 Content-Encoding: x-gzip
(streamconverter problem?)

Yeah the window closses soon after I resume..I don't see any error in the
Javascrip console. I have seen some bugs have been reported similar to this on a
dialup connection. But I am not using dialup here. Also, I have see this problem
while downloading a PDF also.

well basically, I see two possibilities here... either the server decided the
TCP connection has a timeout and closes the connection, so mozilla gets an error
trying to resume; or there's a bug in mozilla's gzip streamconverter...

A packet sniffer log would let us eliminate (or confirm) the first possibility....

I am confirming this bug as I can also reproduce it on Windows XP SP2, Firefox 1.0 .
