when you get a jpeg stream (motion camera server) with content-type: multiplar/x-mixed-replace and the framerate is about 30fps mozilla can show the first image and stop, rendering all images cost a lot cpu and the browser can't show they, after it firefox crash

Reproducible: Always

Steps to Reproduce:
1.open the web site
2.if don't happen miniminize windows
3.if don't happen get a pentium 3 650mhz with 256 mb ram and 16 mb video and try again

Actual Results:  
crash

Expected Results:  
show some images for example with 30fps about 10 fps could run ok without crash

a fps selection system on jpeg multpart images could help like 
max-fps in config (preferences)
the camera stream can be read from http://spadim.com.br:3000/
Could you install with talkback and get a talkback ID for the crash? http://kb.mozillazine.org/Talkback
Keywords: crash
no talkback id created, the cpu level on windows show 99% CPU utilization on firefox and the firefox screen get white with no response so the firefox "CRASH" what can i see when getting jpeg images is that tab icon always change with the jpeg image like showing the fullsize image on browser and resizing the same to show in tab icon when the browser stop the tab icon continue and after browser crash, you can't see it with my stream cause stream can't be bigger than 10fps on internet (ADSL link) if you try with a LAN link and ~30fps you can see the crash
NO IT DOESN'T CRASH. IMAGES DO NOT SHOW UP. THIS IS THE MOST CONFUSING AND USELESS   BUG REPORTING SYSTEM I HAVE EVER SEEN. I AM NOT A COMPUTER ENGINEER. I HAVE A SIMPLE PROBLEM AND I THINK I HAVE DESCRIBED IT AS WELL AS I CAN. I SHALL USE SAFARI AS DEFAULT UNTIL YOU TELL ME THAT YOU HAVE FIXED THE PROBLEM OR SEND ME EXPLICIT (STEP 1, STEP 2, STEP 3 etc)instructions thai i can undersatand and implement

Summary: with many jpeg images on buffer a crash happen → with many jpeg images on buffer a hang happen
i can make a workaround creating a HTML page with
<img src="mjpeg image url">

with this no "crash" happen, i think that ico image on tabs are creating this problem when need to resize the full image 30 frames per second...
I can confirm this problem with all versions of Firefox between 1.5.0 and 1.5.0.4. Note: this problem does not exist on earlier versions.
The original poster is trying to use the http server within "Motion" (http://motion.sourceforge.net/) which streams MJPEG files from a webcam. My experience is that Firefox hangs whenever a stream is viewed, regardless of frame rate i.e. from within the local LAN or across an ADSL link. Firefox running in Windows 2k, 98 and Linux all show the same behaviour. Opera handles these streams perfectly.
(Another issue that *may* be related is that the refresh button had to be pressed  in earlier versions to get the stream to update correctly. Again, Opera doesn't need this).
I have the same problem with Axis cameras with 7 motion jpeg (mjpeg) streams but it doesn't crash the window with the streams.. Instead it prevents pages loading in other tabs or windows whilst the stream is being viewed. Once you navigate away from the stream page all the others load immediately (assuming they haven't timed out--Not checked that). I have not seen in the past pre 2.0. Using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0.
Is this problem still occurring with Firefox 3.0.7 or later in Safe Mode or a new profile?
