[wikipedia.mozdev] strange behaviour with the option "show" set to "only if URL contains"

[Henning Heil]

Hi there!

I just installed the wikipedia toolbar and I like it very much, quite 
useful thing.

One thing I could not handle:

I set the Option "show" > "Only if URL contains" to my wiki URL but the 
toolbar does not disappear on other pages. I did some screenshots:

http://fastview.motorcityone.com/?uid=50 (regular mode, toolbar works as 
expected)
http://fastview.motorcityone.com/?uid=51 (other URL, still visible even 
it should not and therefore violation the settings described above)
http://fastview.motorcityone.com/?uid=52 (trying to hide the toolbar)

The unwanted behaviour is the same even if only one or none tabs are 
open and display a complete different URL (e.g. google).

Can anyone think of what might happen?

Thanks for your support,

Henning
