You're just full of surprises, aren't you?
Although the release of Firefox I have installed is called "Product Version 1.5" the Firefox executable file (firefox.exe) is "File Version 1.8: 2005111116" so I've copied and pasted that info (redundantly), from two sources, so you can pick and choose which and how much information you want to send for analysis.
From "About Mozilla Firefox"= Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8)Gecko/20051111 Firefox/1.5
From ZAP "Entry Detail"= firefox.exe Version 1.8: 2005111116 Last modified date 11/29/2005 23:20:50 File size 6995 KB
Here's some additional information that may, or may not be useful.
Last night (early this morning -yesterday?) as I was getting ready to log off this forum I got a ZAP pop up which looked something like this...
Description: Firefox requested permission to access the internet.
Date / Time: 2006/01/31 00:37:02-6:00 GMT
Type: Repeat Server Program
Program: C:\PROGRAM FILES\MOZILLA FIREFOX\firefox.exe
Source IP: 18.104.22.168:53
Direction: Incoming (accept)
Action Taken: Allowed (once)/Manual
Source DNS: ns1.mindspring.com
The ZAP Programs log entry "Description" is technically correct but misleading unless the additional "Direction" information ("Incoming (accept)) isn't taken into account.
I screen-captured the ZAP pop-up alert 'ballon' and saved it. The actual message on the 'ballon' is "Firefox wants to accept connections from the trusted zone."
Here's what I got when dove into the ZAP "Alerts & Logs" Program Log, found the log entry, right clicked on the log entry, and selected "More Info"...

Firefox wants to accept connections from the Internet or your local network
Firefox is the main program for open source Firefox web browser, which is part of the Mozilla Internet browsing suite. It is normal for this program to request server permission, and it is safe to grant permission.
Here's the URL... it's so long you may have to paste it back together in your browser address field, in order to see the entire SmartDefense Advisor web page for yourself... if you're interested and haven't already seen it a zillion times before.]
This begs the question, "Why would my ISP's DNS server be sending a connection request to my Firefox browser?" Of course, the answer is, "How the heck would I know!?"
My decision was to uncheck "Remember this setting" and "Allow" the connection. And.... Hey! Nothing blew up! (This time ;-)
I spent more than several hours this evening/morning (What day is it?) searching the Mozilla forums, knowledge base, and etc. I found this thread which is similar in content to other scattered post I found throughout the forum...
I don't know if this can and/or should be taken as a definite answer, because I think the Mozillazine forums are like this one... users supporting users... but, it does confirm what I thought and it does contradict the SmartDefense Advisor web page advice.
