This was discussed on Mozillazine
http://forums.mozillazine.org/viewtopic.php?t=119389 regarding
http://www.mcafee.com/us/. When the files are saved to my system and viewed they
render as they should... when uploaded to a server they no longer render
properly. I fixed a couple of minor XHTML and CSS validation errors in the
original and placed them on my server at http://exchangecode.com/mcafee/test.html.

Reproducible: Sometimes
Steps to Reproduce:
1. Copy the files from http://exchangecode.com/mcafee/ locally.
2. Compare test.html when viewed locally to one on the server.
3. 
Actual Results:  
The page is rendered differently most of the time

Expected Results:  
The page should be rendered the same... preferably as it is seen when viewing it
locally.

This same results were experienced with both:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.2) Gecko/20040827
Firefox/0.9.1+
and
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a3) Gecko/20040817

This may have to do with network speed. I have noticed that if I navigate to a
new page and then go back that it renders it properly.

I created another html file and removed the javascript along with the css files
that don't pertain to this issue and the problem is still present.

http://exchangecode.com/mcafee/test2.html

The only files necessary for testing should be the test2.html and default.css...
I am leaving the rest there for now for reference.

When the problem occured I can resize the window and zoom the page and the
problem remains.  DOMI shows that the "missing" DIVs are in the DOM and have a
specified width of 242px but that their computed width is 0px.
The specified style for these DIVs have "display:table; float:left;", yet their
children are "display:block".   With a debug build I get:

###!!! ASSERTION: How'd we get a floated inline frame? The frame ctor should've
dealt with this.: 'aReflowState.mStyleDisplay->mFloats == NS_STYLE_FLOAT_NONE',
file nsLineLayout.cpp, line 1275
Break: at file nsLineLayout.cpp, line 1275

Frame dump:
TableOuter(div)(1)... [state=00010004] [content=0x84c73b8] [sc=0x8517928]<
  Table(div)(1)... [state=00010004] [content=0x84c73b8] [sc=0x85173b0]<
    Text(2)@0x8517d00[0,0,F]  {0,0,0,0} [state=00000426] sc=0x8517cd4<
      ""
    >
  >
>

Yet the content dump looks OK.

I think I've seen this problem before when the intermediate anonymous table
frames fails to appear.

Just wanted to note though it may not be relevant that with the testcase it
appears that it isn't possible to navigate away from the page and then come back
to it to see it render properly where as this is possible when viewing the
mcafee site as well as http://exchangecode.com/mcafee/test2.html. Also, the
testcase doesn't display properly when it is local as well.

Boris this is a dupe, that bug 148810, is of course a diffult to fix bug. The
code here goes through ContentAppended which does not handle pseudo frames
