Ampersand is rewrited to escapced form. Rated 2 out of 5 stars

This addon works in most cases with firefox 11,
But The ampersand characters with cgi-bin parameter is rewrited to escaped format.
So it cause break cgi working.
It occurs significantly in ancient CGI access counter uses with img src tag.

This review is for a previous version of the add-on (0.8.16.1-signed).
