Selenium IDE 1.0.2 in Firefox 3.5 on Mac

I've tried installing Selenium IDE from their website. The newest version - 1.0.2 - installs fine. After restarting Firefox, I go to "Tools" > "Selenium IDE", and this window opens:

No more happens. I can access the menus of Selenium (Create New Test Case, etc.) but clicking 开发者_运维技巧them doesn't have any effect.

I am using Firefox 3.5.3 on Mac OS 10.6.1. The version I installed of Selenium IDE was 1.0.2 from http://release.seleniumhq.org/selenium-ide/1.0.2/

Is there any way to make it work? Or is it just me who cannot make it work?

Generally the conflicting extension are themes, for not having to create a completely clean profile and loose all your add-ons, try using firefox in it's default theme and see if that works better.
