Has no memory of what was removed previously. Make it remove an object, reopen the browser to the same web page and the object returns. Make it so the same object removed is removed for the entire URL. Create a menu icon that lights up when something is blocked by a rule, for easier access. Otherwise this extension is just a bothersome time waster.

I would like to know why it is necessary to agree to personal information being available to the programme, before it can be installed. Are there any security issues associated with this action?
