When I try to connect to my own IP address (127.0.0.1 but also the address on my ethernet link), I can see in a tcpdump (-i lo0) that an RST is send in response to the SYN sent by Firefox. Yet, the tab continues to display "Loading" and in the bottom line it keeps saying "Connecting to ...". In the meantime, the CPU load goes to 100%. When connecting to an external address (on the same network), it also fails to see the RST, but now the CPU stays "normal". I don't see a timeout (waited for at last 2 minutes).
Connecting to an external system on a port with nothing listening gives the expected "Problem loading page" message.
Steps to Reproduce:
1. Make sure there is no webserver listening on http://127.0.0.1:80
2. Open http://127.0.0.1:80
3. Start top in a seperate window and watch the CPU usage go up to 100%
4. See that Firefox does not notice there is no webserver (or any service) at that port
As I have no access to 3.6 (at the moment(, I just added the 3.5 branch (I;m using 3.5.12).
It would be great if you test it again with Firefox4.0beta or a nightly build.
I can't see the problem on Seamonkey trunk on win32 or on FF3.6.9 in Ubuntu.
( I used :90 on my system because there is a webserver on port80 in my case).

Sorry, I don't have access to Firefox4.0beta or a nightly build for FreeBSD.

Firefox 3.6.10 behaves the same as 3.5.9 on my system
firefox-3.6.12 on FreeBSD 8.1 i386 still have this Problem.
netstat shows a handfull connections.
trying to attach with truss, i see a lot
of calls retuning "socket not connected errors".
It might be a problem of an library firefox uses.
The problem still bites:
FreeBSD 8.2-RERELEASE, i386
Same Problem with Firefox-4.0 with all extensions disabled.
FreeBSD 8.2 on i386 and amd64
