You have quite a few extensions installed that can cause problems like that (Adblock Plus, Ghostery).

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

• Don't make any changes on the Safe mode start window.

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

• If you have many extensions then you can first enable half of the extensions to test which half has the problem.

Continue to divide the bad half that still has the issue until you find which one is causing it.

Thanks Cor-el. With your assistance, I was able to track down what's causing the problem.

It's Ghostery. Apparently, it's a problem that they're aware of ... they're working on it ... http://getsatisfaction.com/ghostery/topics/ghostery_2_1_breaks_javascript.

In the meantime, I just have to disable Ghostery in order to run a Jcarousel.

Thanks for your help. It's appreciated.
