Errors in FF 2.0 Rated 1 out of 5 stars
Totally buggy under FF2. Not recommended.
Answering the developer: So you should change the allowed versions if it is not supposed to work in FF2!
Re: Errors in FF 2.0
It is not supposed to be working with FF2 - there is a separate version for FF2 available at https://addons.mozilla.org/en-US/developers/details/4618
