If you can't fit the options screen to your window view, or re-size it, or move it, then this is a useless add-on.

As things go with computers, you need to change to different systems and upgraded browsers. I no longer own the original computer I used with this and Firefox has had multiple upgrades. What once worked no longer does it for me.
