If you click the popup window's "option...", don't you have the add-on option showing with it's name ?
"preferences for xxxxx"
my addon has it's name written here

Another way to do it :
type in your address bar : about:config
then search for "extensions", this will show all the preferences for the extensions, with their names.
(of course that is if the developer registered the option in the right place, he could have registered it to "my.extension_name.option_name" instead of "extensions.extension_name.option_name")
extensions.dta is for downthemall
and
extensions.addblockplus for ... yes
so
the other one should be the one you are looking for.

Again, another way : (maybe need a little knowledge, and an additional add-on installation)
Install
DOM inspector (it's a debugging/dev tools)
Open your popup's "option..." window
Open the DOM inspector "tools/DOM inspector"
select "File/inspect chome document" and pick the option window.
You will have the path to the window option written in your DOM inspector, like "chrome:///content/option.xul
or the path to the real folder it is located if it's an external addon (fille:///c:/user/etc.)
This is just weird there's no other add-on in the addon manager, maybe it's a plugins ? (like cooliris)

It does it in IE8, so maybe it's something to do with bing?
What is bing ? (I didn't google it, I admit)
