FWIW, the entire page seems to be one big Flash widget. I can also reproduce this on Linux with Flash 11.2 so it's not a Flash issue. I can also zoom in/out on other Flash pages so I think this might be a case particular to this website.

I don't see any errors in Error Console to indicate a failure here so I'm not sure how to proceed. Perhaps outreach to the website developer?

Moving this to Tech Evangelism for the time being. Please move back to Layout if this issue is broader than I've characterized it above.

I confirm that this issue is not a regression, it reproduces back to Firefox 4.0.

Hallvord?

http -v GET http://waterlife.nfb.ca/ 'User-Agent:  Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0'

In the body of the page we get both for WebKit and Firefox

<script type="text/javascript">
    var flashvars = { server: "http://waterlife2.nfb.ca/" };
    var params = {
        menu: "false",
        allowfullscreen: "true",
        allowScriptAccess: "always",
        scale: "noscale"
    };
    var attributes = {
      id: "flash",
      name: "flash"
    };

    swfobject.embedSWF("http://waterlife2.nfb.ca/Preloader.swf", "flashcontent", "100%", "100%", "9.0.0","expressInstall.swf", flashvars, params, attributes);

    swffit.fit("flash", 1036, 624);

<!-- Code to set the right tracking code base for the project -->
var NTPT_PGEXTRA = '&ntpg_app=interactive&ntpgi_project=waterlife&ev=interactive&ntpgi_interactive_page=waterlife&ntpg_lg=en';
</script>



They use a JS for fitting the flash in the window size. The script starts with

/**
*	swffit v2.1 (01/18/2009) <http://swffit.millermedeiros.com/>
*	Copyright (c) 2008 Miller Medeiros <http://www.millermedeiros.com/>
*	This software is released under the MIT License <http://www.opensource.org/licenses/mit-license.php>
*/

var swffit = function () {
  var NS = (navigator.appName == 'Netscape') ? true : false,
  WK = (navigator.userAgent.indexOf('WebKit') > 0) ? true : false,
so we are identified with NS = true, WK = false.
The variable "_re" starts undefined and is related to the resize flag.
  function startFit() {
    setSize();
    if (!_re) {
      addResizeEvent(setSize);
      _re = 1
    }
  }


The script has a addResizeEvent and removeResizeEvent

  function addResizeEvent(fn) {
    if (win.addEventListener) {
      win.addEventListener('resize', fn, false)
    } else {
      if (win.attachEvent) {
        win.attachEvent('onresize', fn)
      }
    }
  }

The code executes "win.addEventListener('resize', fn, false)"

What I see (don't have a wheel mouse) is that I can zoom in on http://waterlife.nfb.ca/#/ by pressing [ctrl]+[+]

I have to press it several times and see nothing happen though, from 4th or 6th press or so onwards the Flash is enlarged.

I can not zoom out with [ctrl]+[-] - well, it goes back to original size but never smaller.

On resizing the Flash shrinks with the window until a certain minimum width.

Everything works exactly like it does in Opera (Blink-based). So I don't think I see anything broken - except maybe the slight oddity that you have to press several times before it starts zooming in and can't zoom out beyond normal size.
