Rated 5 out of 5 stars

Its OK now, and there is no need to worry about answering my question. I was misguided but some guru guidance what I had earlier, before adding the YesScript.

I JUST Got iT under:

Tools / Add-ons / Extensions & to add further addresses there is [Options] button.

And it works cool and remembers what is added in the list [ as I read somebody says, it doesn't remember ].

Thanks a lot and Godspeed.

This review is for a previous version of the add-on (1.9). 

Where to find it? in case we need to give some site address to Block? Rated 5 out of 5 stars

I've just added it but I can't see it under Tools/adons/options nor elsewhere in browser's command menus.... I'm using FireFox 18.0.2. have you modified it to work in background or I'm not getting the point?
