No, John - at least on my machine (and I've had a problem or two myself, though nothing to do with Firefox). I too am using version 2.0.07). My operating system is Windows XP Pro.
I did receive an alert from Secunia this morning regarding a low level risk problem with Firefox, the text of which follows:
*********************************** *************
TITLE:
Firefox "-chrome" Parameter Security Issue
SECUNIA ADVISORY ID:
SA26881
VERIFY ADVISORY:
http://secunia.com/advisories/26881/
CRITICAL:
Less critical
IMPACT:
System access
WHERE:
>From remote
SOFTWARE:
Mozilla Firefox 2.0.x
http://secunia.com/product/12434/
Mozilla Firefox 1.x
http://secunia.com/product/4227/
DESCRIPTION:
Mozilla has acknowledged a security issue in Firefox, which
potentially can be exploited by malicious people to compromise a
user's system.
The security issue is caused due to the "-chrome" parameter allowing
execution of arbitrary Javascript script code in chrome context. This
can be exploited to execute arbitrary commands on a user's system e.g.
via applications invoking Firefox with unfiltered command line
arguments.
This is related to:
SA22048
SA25984
The security issue affects Firefox prior to version 2.0.0.7.
SOLUTION:
Update to version 2.0.0.7.
NOTE: Support for Firefox 1.5.0.x has ended June 2007. The vendor
encourages users to upgrade to Firefox 2.

I doubt though, John, (as you are using 2.0.0.7) that this would be the problem.
