Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[ftr]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1

when I open www.nascar.com, my cpu usage immediately increases up to 90+%. will not decrease until I close the tab. Can repeat every time. 

Reproducible: Always

Steps to Reproduce:
1.open tab in firefox.
2.type nascar.com in the address bar. hit enter  
3.page will load and cpu usage steadily rises to and remains 90+%.
Actual Results:  
cpu usage stays high until I close the tab.

Expected Results:  
cpu usage expected to drop back to normal low rate after page finishes loading.

updated to latest Firefox but problem still remains. 

Have had other times when cpu usage stayed high with several tabs open. usually dropped if I closed a few tabs, but I hadn't noted a specific url until now. Point is, there may be other urls that cause this. NASCAR.com does it every time. 
Windows XP sp2...updates done.
Thank you

Select firefox.exe in the big list, right click, properties;
Go to the Threads tab and choose the one with the highest value under "CPU" and click the Stack button

Both ways will get you a stack trace (the first way you can even tellays NPSWF32 that means it's inside of the Macromedia Flash plugin.

If it's not Flash:
Please give us a few Talkback IDs from the first option (just put the TB???? things here) so we can have a guess at where your CPU is spending time.
