I tried akbash's suggestion above: Tools/Options/Web Features/Advanced, uncheck "Raise or Lower Windows", and a popup/under still came from Netscape.com when the tab was closed.

You're a tough nut to crack. Well, first things first. I think you're referring to this post of mine

That [checkbox] prevents a website from hiding a newly opened window behind your window; it makes all popunders be popups.

After re-reading that twice more I'm quite certain I didn't promise that this checkbox would stop popup windows from appearing at all. The only functionality I claim for it is just as it describes itself.

I have explained what I believe your problem to be, from my vantage here on Clairvoyant Island, and what must be done to fix it. You seem to be waiting for a different solution. I know of only the one.

I don't understand the cause of this, but I know that I started with my Moz1.7.3 bookmarks file imported in FF. The 1.7.3 file had a bookmark, which saved all Tabs, and would open them when double click. That was the source of my Tabs, and of my headaches. I had suspected netscape.com n so I first removed all Tabs, and reintroduced them in groups, saving my settings (current pages) inafter each readdition. Netscape.com was the last one, and I had a newly built set of Tabs, not derived from 1.7.3. And, there has been no problem.
I had the same problem when I tried to create a different set, and using the open in tabs option for the folder in Manage bookmarks. One site in the different selection was a bankrate place, with the same ar.atwola.com address. I close 1.0, and there was the page. But, everything is fine, because I did not save this new set. I don't think it is netscape.com, but something else.
I don't have the website, since I deleted it, along with my 1.7 Tabs bookmark. But, everything is still present in Moz1.7.3.
I never used any extention, and if there is a problem, it is not directly connected with netscape.com. All is well now. Sort of.
I have two separate profiles for 0.9.3 and 1,0, but everything seems synchronized, like the addition of Tabs or bookmarks.
I do not want to carry on this conversation for a Preview, but I am seeing too many thing which are wrong.

I have found an example where I can get an unrequested pop-up window to reliably appear in Mozilla Firefox 1.0 PR in spite of precautions:

1) Open the page http://www.iarchitect.com/ in a browser tab.
2) Close the tab.
3) Two pop-up windows will appear the instant the tab is closed.

This is the complete list of known, verifiable weaknesses:

[*]Closing the webpage in some way: this is a regression in Firefox 0.10 PR1 that I claimed had been fixed in recent builds, but another variant has turned up that isn't fixed at time of writing.

This appears to be the weakness related to these occurrences.

This is precisely what happens at Netscape.com, as soon as the window or tab is closed, the popup/under appears.

I'm wondering... perhaps some web sites have found a way to circumvent popup blockers now.

I confirm that iarchitect.com site opens two windows on closing FF1.0rc.
However there have been no problems with home.netscape.com
Any other netscape.com page? At this points I have 16 tabs, which I save in Tools|Options|General|Use Current Pages. I did not save the iarchitect.com.

Same here. The bug report contains more examples:

Popup blocker for onunload does not work when closing a window/tab.

Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

The popup blocker for onunload events works when leaving a page (by using e.g.
the back button), but not when closing a tab. I've seen the problem on several
sites now, including the "Come & Go Test" at http://www.popuptest.com/

Reproducible: Always
Steps to Reproduce:
1. Go to http://www.popuptest.com/
2. Open the link "Come & Go Test" in a new tab <snip>.
3. Go to the new tab (if needed) and close it.

Actual Results:
A popup window is opened.

This is the smallest example that exhibits the problem on:

• ...
• Plugins like Flash and Java: these are allowed by default to open new windows, but there's a pref for disabling even that.

I just discovered that not all Flash popups are blocked, so I have to recant that bit.
