Bug Description

Binary package hint: firefox-3.0

The following example shows a discrepancy when viewed in firefox 2 vs firefox 3.

  http://people.ubuntu.com/~bryce/tmp/firefox-3-js-issue.html

The file includes an external javascript .js file, using the following syntax:

  <script src="firefox-3-js-issue.js" />

pitti and cjwatson noticed that http://people.ubuntu.com/~bryce/Plots/plots-0.7.html does not render in FF3. Once I inlined all the javascript it began working: http://people.ubuntu.com/~bryce/Plots/

Could this be related to a missing doctype? I'm not sure if the shorttag syntax (<foo />) has to be interpreted correctly when in Quirks mode. (see also: http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fpeople.ubuntu.com%2F~bryce%2Ftmp%2Ffirefox-3-js-issue.html)

Actually it's not only that the doctype is missing from http://people.ubuntu.com/~bryce/tmp/firefox-3-js-issue.html, but this page doesn't even have a root-element (should be a <html xmlns="http://www.w3.org/1999/xhtml">-tag in this case).
http://people.ubuntu.com/~bryce/Plots/plots-0.7.html has a root-element, but it doesn't specify the xmlns, which probably causes <bar />- tags to be misinterpreted.
I have had the experience that a doctype is not absolutely necessary in most browsers, but nonetheless it's required by the W3C specification (http://www.w3.org/TR/xhtml11/conformance.html#s_conform).
I think it is relatively likely that this is caused by quirks-mode. I have often had cases (mostly in IE that doesn't really like XHTML) where <script /> tags spanned the whole rest of the document, which lead to empty pages and other interesting results.

<script/> is not proper HTML. See https://bugzilla.mozilla.org/show_bug.cgi?id=412114

I have a bug on my school schedule. There is an external javascript inside and it doesn't launch. The address is : http://edt.polytech.unice.fr .

I think that the javascript should be started with this line <script src="Accueil-24152.js"></script>. Is it missing something on the page ? or is it a real bug on Firefox 3 ?
