When attempting to book a flight at www.aircanada.com, selecting certain booking options and clicking "NEXT" at the "Customize Your Departing Flight" page exposes a major memory leak in Firefox. Memory consumption grows interminably and the browser consumes 100 % CPU during the process.
Reproducible: Always
Steps to Reproduce:
Please follow the below steps EXACTLY:
1. Launch Windows Task Manager
2. Launch Fx and visit www.aircanada.com
3. On the "Welcome aboard" page, select "Canada" and "English" then click "GO"
4. For flight, enter leaving from "YYC" and going to "YYZ"
5. Select a departure date of Aug 1st and return date of Aug 31st then click "SEARCH"
6. Select a departing and returning "Tango" flight, each under "Connecting Flights", then click "CONTINUE"
7. On the "Customize Your Departing Flight" page, leave the defaults and click "NEXT"
8. Observer the Fx process in Windows Task Manager
Actual Results:
Firefox consumes memory and CPU indefinitely.
Summary: Major memory leak at aircanada.com → Major memory leak and 100 % CPU at aircanada.com

Using a smoketest build from last night, I see the problem happening in Linux too: 95% CPU, and the VMSize increases by about 50MB *per second* on my Athlon-64 3500+ with 2 gigs of physical memory.

BTW, I'm using the default (unhacked) "Minefield" UA, and aircanada.com still treated me exactly as described.

It doesn't always crash on 2008032605, sometimes it just goes from 50MB to ~600MB and then it drops and is responsive again.

Confirmed. Happened to me. >600MB of RAM usage, 100% CPU and then it stabilized after a while back to normal and 45MB or RAM
Bug confirmed also on:
Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9b4) Gecko/2008030714 Firefox/3.0b4
In few seconds RAM usage growin' up to ~600 MB and firefox.exe use two CPU cores at 100%. After 6-8 seconds, memory and CPU usage goes down to normal value.

Leak Gauge (http://wiki.mozilla.org/QA:Home_Page:Firefox_3.0_TestPlan:Leaks:LeakTesting-How-To)shows no Memory Leak here , but i also can reproduce the high cpu load.

I can repo the run-away memory, in the statusbar I saw 'Waiting for s0.bluestreak.com Consumed 99% of memory, if you waint long enough the page will show 'Done' and memory is released. CPU is 100% and on Vista goes Not Responding several times before it either loads the ad, or times out.
In the View Page info for bluestreak I find:
https://s0.bluestreak.com/ix.e?bb&t=21038
a 1px x 1px image (web-bug?)
Didn't we something similiar with a ad supplier doing this very thing recently?
