Firefox Javascript Error / Oddity / Weirdness. Any Explanations?

Question

If you view this page...
http://eastlondondance.org/admin/MozillaProblem/example.php
...you'll find that there are no errors but that the functionality is not working.

The last dropdown is not being populated with options like the other 2. This however works on Safari, Chrome and IE.

What gives? Why isn't it working on Firefox Linux, PC or Mac but is on all other browsers? Is it a problem with the code or a problem with Firefox?

Any help is much appreciated.

cheers, George

It is working properly. Didn't understood what is the problem. — Ashwin, Jan 11 '12 at 12:52
Working properly in FF9 (Windows). Can you mention which version of FF are you facing problem in? — sv_in, Jan 11 '12 at 12:54
@Ash in firefox the final dropdown is unpopulated in FF 8.0.1 for me anyway — benni_mac_b, Jan 11 '12 at 12:54
@benni_mac_b - I check in chrome 16 and FF 8.01. It is working properly. — Ashwin, Jan 11 '12 at 12:58
This is not working for me in Firefox 9 on Mac, Linux and PC hence the post. The answer, weirdly fixes it. — daktau, Jan 11 '12 at 13:58

Firefox is having problems with the variable name of performance. While I'm not certain why this is, renaming this to anything else will allow it to display in firefox. In the example below I renamed it from performance to performancex.

Example: http://benjaminhopkins.co.uk/stackoverflow/firefox.html

From the comments above seems not everyone see the problem? Maybe it could be a extension / plugin causing the issue. Using the developer toolbar and hovering performance firefox reveals the following:

Performance { constructor=Performance,
              timing=PerformanceTiming, 
              navigation=PerformanceNavigation}

that's interesting-- those kinds of errors can really drive you nuts. – ek_ny Jan 11 '12 at 13:43
Thanks a lot I have amended the code so that it now does not use the ?keyword? performance. A weird one certainly! – daktau Jan 11 '12 at 13:54
