[Project_owners] access js variables in extension

[joe ertaba]

Hi

I wounder if there is any way to get variable of current tab html page and
use them in extension. e.g:

<script type="text/javascript">
 var bb="bbb";
</script>


P.S: I test content.wrappedJSObject.bb but seems that it doesn't work! any
idea ?
