very poor ! disables js but does not enable

This review is for a previous version of the add-on (0.0.1). 

Version 0.0.2 fixes at least one bug.

If that is the one you discovered? I'll never know.
Because your comment does not give enough information about the bug, and other installed Add-Ons, that could possibly interfere.
