Thanks for contacting us, buy could you give us a little more information on what you mean by getting stuck? Is the button itself not working, for example, but when you mouseover it, the hover color isn't changing? What is the URL (i.e. example.typepad.com) of your blog?
What version of Firefox are you using? Do you see the same behaviour on other browsers?
If you're experiencing problems on other sites too, like her on Get Satisfaction, you may want to try temporarily disabling any add-ons that you might have installed since it sounds like one of them may be causing a conflict with drop down menus.
