188403 - frames not always loaded correctly (something to do with caching?)

Status: RESOLVED INVALID

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[IMSoP]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030109
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030109

After installing a new nightly build, certain pages which used framesets stopped
loading correctly.  Specifically, the first time I load a frameset only one
frame is rendered, the others remaining as completely blank areas of the window.
 On subsequent loads, however, further frames sometimes appear, up to the whole
page being displayed correctly.

At first, I had problems reproducing this bug reliably, and many of the test
cases I produced failed to exhibit the same behaviour.  However, it seems to be
related in some way to the cached status of the subframes, as I can reliably get
a single-frame behaviour if I clear my cache.

The only related bug I found is bug 18297, but the current explanation for that
involves Java and/or JavaScript, whereas I have successfully reproduced this
with pages that use neither.  I have not provided a testcase other than the URL,
as it has proved difficult to produce one, but the source of the frameset at the
URL provides a fairly clear case.

Reproducible: Always

Steps to Reproduce:
1.Clear the browser's cache using the preferences window [if the page has
already been visited]
2.Go to http://www.the-cutting-edge.demon.co.uk/o/index.html (or any page that
uses a similar arrangement of frames)

Actual Results:  
Only the top-left frame loaded, the rest of the page remaining white.

Expected Results:  
Four frames should load, filling the entire window.

OK, it seems I've been a fool, and this isn't a bug in mozilla at all, but an
odd firewall problem which happened to crop up at the same time as installing
the new build.

Sorry for wasting anyone's time - including mine, although it gave me an excuse
to look into a couple of things...
