Those funny extensions one I don't know, but if it's JavaScript
and you are using Firefox, you can get an extension called JSView.
This can grab all the JavaScript codes for you to analyze.
And again, if you are using Firefox, see the sticky on this forum
for overcoming "the cannot right click" syndrome in Firefox.
Another way to get it to cache, copy and paste the source where it
points to, like for those funny extensions... I did that, it's in
cache, but there's no way I can view it without internet -_-
