As I am currently using a dial-up connection for browsing the internet, I recently found out that under some circumstances - which I cannot specify further - the download manager of Firefox 3 Beta 4 schows negative values for the download speed

Reproducible: Sometimes

Steps to Reproduce:
1. Use a dial-up connection
2. Download some file
3. Look at the download speed shown
Actual Results:  
Download is stuck

Expected Results:  
A file finished downloading - what else^^?

I can provide a screenshot (German version of Firefox, hope it doesn't matter) at http://loadpic.de/9D8HIEU6I.jpg

I saw this today when saving a webpage with many large images.

I was running a debug build on a Windows 7 VM.  Maybe this happens on slow computers / with slow builds?

I also got an assertion to the tune of "no bytes consumed after ondataavailable call".

changeset bb0699c9743a, Windows 7 x86-32, debug build.
Summary: Download manager shows negative download speed values with dial-up connection → Download manager shows negative download speed values
For me the speed was -452899 bytes/sec, which is close to -1 * my actual download speed.

Happens to me regularly when saving a web page, and I'm using broadband.
On Wi-fi, 
download speeds were at a maximum of 18-25 KB/sec 
and around -3000 to -5000 bytes/sec towards the end of the download.
FF 19.0.2 release

I have this issue when downloading the 720p copy of this video from Youtube http://www.youtube.com/watch?feature=player_embedded&v=opqO9PAzyzM

The total download size can not be determined and in the title bar of the download manager as well as on the taskbar for it it will display the % complete prefixed with a minus sign.

Don't ask me why it's showing a percentage completed when it can't determine the total download size, I don't have the answer to that.

Also, this bug is six years old now. Do people still experience it? (I'm not a Firefox user any more)
This error hasn't reoccurred to me since FF 20+ release
Please add a comment if anyone still saw this error since Firefox20

I've seen it once in FF 32.0.1, but I'd have a hard time reproducing it.
This can only be fixed if we find a way to reproduce it ...
