[Suggestion] Can you add an option that only apply the effect to selected websites?
I really want an option that can allow me to select websites to apply the effect of this add-on.
For example, I have a following list: "facebook.com, youtube.com". And I want the add-on to only change the user agent when I surf these website. Websites that aren't in the list will not be affected by the add-on.
Could you do it?
