From Bugzilla Helper: User-Agent: Mozilla/4.72 [en] (Win98; U) BuildID: 2000041805 A nice feature of Mozilla would be to add an option to preferences whereby a user can disable the ability of a web-site to spawn a new browser window when that site is exited (either by going to another URL or closing the window) Reproducible: Always Steps to Reproduce: 1. Go to the URL 2. Close it. Actual Results: A new browser window is spawned on exit. I don't in anyway endorse the site i've used as an example. I don't use it either; I just did a search for some 'warez' sites and closed them until I found one that spawned a new window on exit. An option to disable the ability of a website to open more windows on exit would be great.

this is covered by bug 7380 or maybe more specifically bug 858. *** This bug has been marked as a duplicate of 858 ***

I don't think this is a dup

I don't *think* it's a duplicate, but I don't want to trouble anyone any more than I have to, so I won't press this. Thanks anyway! :-)

I agree, this is a dupe. verified.

If this is marked as a duplicate of a fixed bug, does that mean that there's already an option to disable window.open in onunload/onclose events?

davidr8@home.com, yes, I think this is the case. take a look at http: //www.mozilla.org/projects/security/components/configPolicy.html

I really don't think this is a dup of bug 858. It is a dup of bug 33448, though.

Err, should have said I was reopening the bug when I made that last change. Anyways, *** This bug has been marked as a duplicate of 33448 ***

Bug 33448 covers closing windows, and not browsing away from urls, however I'm not sure that browsing away from urls triggers an event. vrfy dupe. If when that bug is fixed it can be shown that we don't handle that case please create a testcase and attach it somewhere (possibly here, although we might have a bug for it elsewhere).
