BTW,
	I had previously installed the flash plugin from macromedia.com.  I searched for anything left behind that might be fritzing firefox, but I can't find anything.
	Besides this little bug, flash seems to be working fine.
	My friend is using the same netscape-flash and (I think) the same version of firefox, and he doesn't have this problem, but nothing shows up under his plugins dialog.
	The about:plugins page does load and looks like this:

Shockwave Flash
MIME Type 	Description 	Suffixes 	Enabled
application/x-shockwave-flash 	Shockwave Flash 	swf 	Yes
application/futuresplash 	FutureSplash Player 	spl 	Yes

Default Plugin
MIME Type 	Description 	Suffixes 	Enabled
* 	All types 	.* 	No

Update:

It looks like this bug is actually related to iptables.  When iptables is running, firefox crashes in the situation above and evolution-2.0.2-r1 crashes whenever I click the dropdown by an attachment.

It doesn't make sense to me that these crashes would be related to iptables settings, but here are the settings, nonetheless:

Chain INPUT (policy DROP)
target     prot opt source               destination         
ACCEPT     all  --  anywhere             anywhere            state RELATED,ESTABLISHED

and under the nat table:

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination         
SNAT       all  --  anywhere             anywhere            to:10.31.180.56

One other issue that might clear things up a bit:

When visiting gentoo-portage.com or linuxcompatible.org in firefox with iptables running, independent of whether /proc/sys/net/ipv4/ip_forward is on, the tops of the pages load immediately and then the content doesn't load for 3-5 mins.  Right after /etc/init.d/iptables stop, even in the middle of a frozen load, the pages load properly again.  Firefox and evolution also unfreeze if they're frozen when iptables goes down.  Hope that helps.

Stale bug, reopen if this is still an issue with up-to-date firefox/iptables/whatnot versions...
