Here's a follow-up post on things to try that I made to the Ubuntu
forums:

Several more ideas about this to bounce off everyone's head:

a) (From my local Linux guru): "Try turning off ipv6 in firefox. It
seemed faster for me once I did this, the other issues I'll have to
think about a bit more."

To turn off IPv6:
Open Firefox
Type about:config in your url bar.
In the "filter" bar that appears on that "page", type IPv6.
Set network.dns.disableIPv6 to True

b) Try creating a test profile which is not set in Firefox/Mozilla
default folder for profiles but is not within a Scramdisk container, and
see if the problem replicates. That might distinguish between a purely
Firefox problem or a Scramdisk problem;

c) Likewise, set all the profiles back in their default directory,
/.mozilla, then try moving the entire /.mozilla folder to the encrypted
directory. Then delete the original under /home/user and create a link
under that pointing to the /.mozilla folder within the encrypted
directory (which is what I do for evolution, pan, and pidgin, and it
seems to work fine).

d) As these are TrueCrypt containers, download and open them with
Truecrypt (the new GUI version) and see if the error repeats;

e) While I don't see this problem on two boxes running Gutsy, I hasten
to add that these two boxes are desktops, not laptops, and I can see
some differences just in normal operation switching between users
between the two, with no Scramdisk containers open (these differences
replicate on my Linux guru's friend Dell Inspiron 1525N, and he thinks
they might be because the video card isn't fully supported). He says
that upgrading to Hardy might then be the simplest answer.

f) Could this be a problem (at least with Firefox telling me that it's
still running when Ubuntu says it's not) with Flash?

Anyway, I'd be open to more ideas. I could live with this problem if I
could only figure when Firefox tells me that it can't open a new window
because it's still running, even though it's closed, how to kill
whatever app is causing the mischief in a terminal window. Then I could
at least avoid restarting the computer, which is a pain.
