Carlos: Does it work in Fx 4 if you spoof your UA string as Fx 3.6.15?

Does it work in any other browsers based on Gecko 2 (say, a Seamonkey build)? For that matter, does it work in the latest release of Seamonkey?

Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.17) Gecko/20110123 SeaMonkey/2.0.12 WORKS
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b13pre) Gecko/20110308 Firefox/4.0b13pre SeaMonkey/2.1b3pre FAILS

I tried spoofing Firefox 4 as 3.6 and IE8, but did not work. So is not tech evangelism issue?

It sounds like it could still be a TE issue, but the cause is definitely a Gecko change. I'm going to kick this over to Firefox for further triage and if it turns out to be a TE issue, it may end up back here.

Carlos: If you can figure out exactly what nightly Firefox build broke it, that would help a lot.

I dunno about the video bit (since I see no video when I load the page in 3.6), but the menu issue is evangelism.  As the error console says:

Error: assignment to undeclared variable edge
Source File: http://video.ufc.tv/ufc_system_assets_20110307/js/jquery.mainMenu.js
Line: 41

And indeed, the script at that url starts with:

  "use strict";

and then later has:

  function initializeMainMenu(domObj, opts) {
    var links = domObj.find("." + opts.menuItemClass)
    edge = domObj.find("." + opts.menuEdgeClass);

where "edge" is not a declared variable.  So the menu is never initialized.

The regression range in comment 4 includes a TM merge which has this changeset in it:

  Bug 514560: Forbid assignments to undeclared variables in strict mode code.

Working fine in Firefox 4

Comment 7

[Chris Lawson (gone)]

It looks like the problem in comment 5 still exists in the code, though they may not be using that particular code any more. (I don't have time to investigate further at the moment.)

However, if everything originally filed in this bug is fixed, that's good enough for me.
