342905 - Refreshing while iframes are loading leads to mixed up iframe source.

Status: RESOLVED DUPLICATE of bug 279048

(Firefox :: General, defect)

Description

[Brian Moon]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4

We host several ads on our site that use iframes.  We started noticing that sometimes, the contents of these frames would be mixed up.  At first we assumed the ads themselves were to blame.  However, upon careful (and tedious) testing, we narrowed it down to an error with refreshing a page.

Reproducible: Always

Steps to Reproduce:
1. create a page that includes a random iframe source
2. refresh quickly, before iframe is fully loaded.
3. Note that the proper iframe is not always displayed.

Actual Results:  
Wrong iframe contents displayed

Expected Results:  
iframe contetns should match source of iframe element

I will attach a test case

Almost sounds bug number 295813. We see the same type of problem (IFRAME content in the wrong IFRAME on our site as well).

We're delivering an IFRAME based ad solution to a large number of web publishers' sites and we've been seeing exactly this random content juggling within the various IFRAMES on the page following page reload.

This is precisely as reported in #295813 as a result of problems identified on Forbes.com. Co-incidently we're deploying our ad technology onto Forbes and have seen the same problems there, despite the closing comments on 295813 indicate that it might have been solved. 

This with Firefox 1.5.0.7.

Yes, the problem still persist  with 2.0.0.11, even with the nightly build of 3.x from 12-04-2007.
I have added a test case files and comment to bug # 315891 (which seemed to be related before I found this one)
