[Bug 296937] [NEW] Firefox not rendering pages from Windows web server correctly

[Bob Kline]

Public bug reported:

Binary package hint: firefox-3.0

Firefox 3.0.3 on Ubuntu 10.4 is rendering the same HTML page differently
depending on which server it gets the page from, and if it gets the page
from a Windows server, it's not rendering the page correctly.  Now, I'm
no more a fan of Windows than the next Ubuntu user, but it's not
practical (yet) to avoid every site hosted on a Windows server.  I have
attached a screenshot showing what the page looks like when it's served
up by Windows [1], and I'll attach another screenshot showing the exact
same page pulled from a Linux server.[2]  Note, for example, that when
the page is pulled from the Windows server the CSS for displaying the
borders between cells is not honored for all of the cells ("Jim's Juice"
and "Crocinic Acid" are in separate cells, but you can't tell that from
what Firefox displays - though you can if you look at the HTML source).

Here are the HTTP headers coming from the Windows web server (as
reported by wget):

$ wget -S -O repro-from-windows.html "http://mahler.nci.nih.gov/firefox-on-ubuntu-repro.html"

Same thing for the page from the Linux server:

The version of Firefox is 3.0.3+build1+nobinonly-0ubuntu0.8.04.1.  This
problem is not present for Firefox 3.0.3 on Windows, and I can get other
browsers on the same Ubuntu client to behave correctly, so this is
specific to Firefox on Ubuntu.
