From the page source: 
onmouseover="mouseOver(this,'cellOver')" class="menu"><a href="http://www.aircanada.com/en/offers/">Special&amp;nbspOffers</a></td><td dragover="true" 

So Firefox Trunk is not wrong here but 1.5.0.3 is.

 -> moving to Core/HTML:Parser

The menu is built dynamically, using a function which does bad UA-sniffing (looks for "Firefox", which trunk builds no longer have in their UA string).

http://www.aircanada.com/shared/includes/common/nav_top/acoNavButtons.js :

function getButtonText(sometext){
 var agent = navigator.userAgent.toLowerCase(); 
 if(( agent.indexOf("netscape") != -1) || (agent.indexOf('firefox')!=-1)) {
 	if(sometext.match("&nbsp") == "&nbsp"){
		return sometext.replace("&nbsp"," ");
	}
 }
 return sometext;
}

So this is either Tech Evang or INVALID.

See bug 334756 for details on that, BTW.

Indeed, someone commented out that sniffing function:

function getButtonText(sometext){
/* var agent = navigator.userAgent.toLowerCase(); 
 if(( agent.indexOf("netscape") != -1) || (agent.indexOf('firefox')!=-1)) {
 	if(sometext.match("&nbsp") == "&nbsp"){
		return sometext.replace("&nbsp"," ");
	}
 }*/
 return sometext;
}

Resolving WORKSFORME.

This was pretty clearly FIXED, as far as I can tell, by commenting out the sniffing. Fixing resolution and verifying.
