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.
