I still cann't find a solution from your article. So I decide to use the userstyle instead.However, it seems to be incompatible with the style inspector in Firefox 10(App button -- web developer -- inspector). The inspector panel disappers when I inspect an element in any page.This review is for a previous version of the add-on (1.1.1-signed.1-signed).

I cannot install this addon either,because of an error message: A better firefox addon bar cannot be installed because Firefox cannot modify the needed file.
I try to search in the Internet,I find that may be the answer:
It seems that some intermediate file of the installation process is being created with a name longer than the maximum supported length and then the installation process fails.
Your add-on name may be too long in the internal.
