Automatically removes specific cookies on indicated URLs.

Cookie Sniper is a tool to remove cookies automatically using a black-list. You tell an URL where to search and the name of the cookie and this add-on will remove the indicated cookie at every page reload.

The purpose of Cookie Sniper is to remove cookies from a website with a minimal impact. It is not good as an anti-tracking tool for the whole internet but can be helpful to fix errors or bad behaviors on specific websites.
