Convergence - javascript error when customizing banner

Question

I've successfully extended the Convergence javascript in 3 places, but when I try to extend the Banner widget I am running into an error.
I followed the instructions for modifying the Banner here:
http://wikis.sun.com/display/CommSuite/Customizing+the+Convergence+Banner
I restarted the appserver, cleared my browser cache, and even tried another browser.
This is the error that shows up in FireBug:

Aha! It was caused by the AdBlock Plus FireFox extension. Disabling ABP for the domain caused the page to work again (after clearing the browser cache).One suggestion of a colleague regarding ABP was to check whether you are loading any remote images/files etc. via your "../layout/css/wisc.css" file?Good suggestion. But no, they are all relative local paths.
Is there a way that Convergence can be modified either:
- to not exhibit this behavior with ABP? (since this isn't an ad, this behavior might be a bug with ABP or Convergence)Without working out why ABP triggered I can't provided any suggested fixes.So, this doesn't happen to you?
- or detect if ABP is running and warn the user that the client may not function?By definition, an Ad blocking product should not be detectable, otherwise this knowledge could then be used by the web-master for nefarious purposes.
That being said a quick google search showed a few ways to detect add-blocking software e.g.
http://blog.taragana.com/index.php/archive/how-to-detect-adblock-plus/
You could then update the "warning" div on the login screen (login.js) in the same fashion as Convergence currently does when firebug is enabled.
if (console["firebug"]) {
dojo.byId("warning").innerHTML=l10n.login_firebug_on;
ok. I'll keep that in mind if it becomes a problem.
Thanks for your help.
