At first we thought it was an array length issue but when you alert the style sheet it looks like it is there. There are only five style sheets but there are six in the array. Reproducible: Always Steps to Reproduce: 1. Follow the url given above 2. once loaded resize the window and you will see the canvas renderer as they are suppose to so this bug happens on first load but not on subsequent window size changes or clicking on the tabs for the other services. Actual Results: When the null pointer is thrown the page stops rendering the canvases which is how we build the menus and headers. Try the following URL in FireFox 2.x to see our "white labeled" version for HomePoints; http://www.allconnect.com/shopping/ssc-homeservices-trashRemoval/trashRemoval.html?zip=30005&referrerID=31672& Now you can see how the canvases should respond. Expected Results: described above or use FF 2.x More urls to try; ALLCONNECT DEFAULT: http://www.allconnect.com/shopping/ssc-homeservices-trashRemoval/trashRemoval.html?zip=30005&referrerID=31290& RELIANT ENERGY: http://www.allconnect.com/shopping/ssc-homeservices-trashRemoval/trashRemoval.html?zip=30005&referrerID=31570& SMUD: http://www.allconnect.com/shopping/ssc-homeservices-trashRemoval/trashRemoval.html?zip=30005&referrerID=26420& HOMEPOINTS: http://www.allconnect.com/shopping/ssc-homeservices-trashRemoval/trashRemoval.html?zip=30005&referrerID=31672&

Regression range for this is http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=1193168220&maxdate=1193177579 -> Bug 397427.

.href is null for inline stylesheets per spec. The page in question has five external stylesheets, and one inline stylesheet (the last one). So you get the effect described in comment 0. What happened here is that we fixed bug 74281 as part of the fix for bug 397427. And the site happened to be relying on the old (buggy) behavior instead of being written to the DOM Style specification...
