Same thing with Firefox 32 on Linux and with Firefox OS.

bootstrap.css styles body with display:none :

body{
-webkit-touch-callout:none;
-webkit-text-size-adjust:none;
-webkit-tap-highlight-color:rgba(0,0,0,0);
display:none;
font-size:12px;
opacity:none
}

I suppose some JS supposed to undo that is failing.

In script.min.js, method onAppStart():

$("body").show();

The show() call fails because this code:

      if (a.style) {
        b = a.style.display;
        if (!c._data(a, 'olddisplay') && b === 'none') b = a.style.display = '';
        b === '' && c.css(a, 'display') === 'none' && c._data(a, 'olddisplay', za(a.nodeName))
      }
    }
    for (d = 0; d < e; d++) {
      a = this[d];
      if (a.style) {
        b = a.style.display;
        if (b === '' || b === 'none') a.style.display = c._data(a, 'olddisplay') || ''
      }
    }

more precisely the za(a.nodeName) call, tries to read the "default" style for an element by adding an IFRAME to the document, appending an element inside it and calling into jQuery's css() method. For some reason this seems to return 'undefined' for the BODY element's display property in Firefox. Looks like a bug in Firefox's layout / CSSOM code, compare http://jsfiddle.net/zn7akfxg/ in Gecko and WebKit-based browsers.

https://bugzilla.mozilla.org/show_bug.cgi?id=548397 gotcha. Not an issue for outreach, so I'll close this webcompat.com bug.

[Rudloff]

I think this raises another issue: Their website can't be used at all with JavaScript disabled.

[hallvors]

Absolutely. Not exactly best practise and non-obtrusive enhancements over there.. :-/

[adamopenweb]

Just to add, there is an open bug for Firefox OS and Futureshope/Bestbuy. https://bugzilla.mozilla.org/show_bug.cgi?id=974529. First contact attempt wasn't successful if anyone knows someone there.

I'm not so sure that this is https://bugzilla.mozilla.org/show_bug.cgi?id=548397. This was a bug that was fixed in jQuery 1.8.3. See #663 (comment) for more info.

Future Shop stores operate as a division of Burnaby-based Best Buy Canada Ltd., a wholly-owned subsidiary of Best Buy Co., Inc. (NYSE:BBY).

so we need to find best buy I guess.
There is @bestbuycom but the last update is one year old with @agent462
There is @BestBuyAPIs more encouraging with the latest updates (hours away) by @cmlizama and @jkap

That could help for finding the right persons for all these bugs:

• This one Mobile Futureshop Canada blank page #300
• m.futureshop.ca - Shows a blank page #626
• m.futureshop.ca - blank page #610
• m.futureshop.ca - site is entirely hosed under our mobile UA #663

[karlcow]

I wonder if @fernando-fanfair or @albrec or @bestbuycom or @agent462 or @anpainte
can help us contact the right person at BestBuy for solving the issue.

As explained in #663

"The suggested fix would be to update to jQuery >= 1.8.3, OR to change $("body").show(); to $("body").css("display", "block");"
