After getting a disconnect from my dialup service and then reconnecting and then
resume using the same Firefox instance that was used before the disconnect, I
get around an 84-97% CPU usage that will not go down. I then have to exit
Firefox and restart it. The problem appears to be in the disconnect and not the
reconnect.

Reproducible: Always
Steps to Reproduce:
1.Disconnect from service either manually or by accident (problem may only work
with dialup)
2.Take a glance at the CPU usage in the processes list.

Actual Results:  
84-97% CPU Usage that will not go down.

Expected Results:  
...I think it's pretty obvious what it should have done.

I am using the Noia 2.0 eXtreme Theme Version 2.79 but I believe the bug still
happens with any theme.

System Specs.
XP Home Service Pack 2
P3 Celeron 566MHZ
320MB SDRAM
nVidia Geforce4 MX 440 SE Driver Version 70.41 Beta
...Me again. The cause for it appears to be Norton AntiVirus 2004 Pro. After I
installed Norton AntiVirus 2005, it appears to not do this anymore.
Marking as WORKSFORME. Reopen if the problem appears again.

I confirm this bug. 
The bug is not reproducible always for me, just in about 50% of cases.

a programmer..): http://img259.echo.cx/img259/3087/ff100cpuload1ls.png

After a disconnect if I set FF to offline mode, the CPU activity ceases. But as
soon I go back online FF continues to waste CPU time, even after a reconnect. 
This bug is haunting me again and again :( Fix it please.

1) Does it happen with the latest trunk (http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/pacifica-trunk/)?
2) Do you have any FF extensions installed?
3) Does it happen under the safe mode of FF?

Don't know. Sorry.

> 2) Do you have any FF extensions installed?

No one.

How can I start FF in safe mode?

Start Menu -> Programs -> Firefox -> Firefox (Safe Mode)

Anyway unless you try the latest trunk or branch there's little chance you get help in a short time...

I have installed 1.5.0.3 version and this bug still present.

1. Start FF. CPU usage is normal.
2. Connect to internet (dial-up).
3. Open some website.
4. Disconnect from Internet.
5. FF start using 100% CPU.
6. Connect to Internet again.
7. FF still using 100% CPU.
8. Switch to "Offile mode" in FF, and FF stop using 100% CPU.
9. Switch to "Online mode" and FF start using 100% CPU.

I have not extentions. Installed only native FF.
I have Windows XP SP2 without any updates.

This might be identical to bug 327050 which has some additional information in it. It's not specific to dialup, however, but any network connection.
Do you guys with this problem have any firewall software working background? Comment #1 suggests it's one of the sources for this bug.
I have two machines on which I can reproduce this (actually, three). One is running Windows firewall in its default configuration, the other runs ZoneLabs Integrity.

On the latter, I turned off both firewalls and re-tested. Same thing happens.

Both machines also have different AntiVirus software (Symantec & Avast). If I disable Avast, no difference. (I can't disable Symantec, but there's no evidence to suggest it's the culprit at this point.)
