I'm hesitant to install because it requests permission to clear my cookies, history and so forth. Cookies in particular, I normally clear manually and, when possible, selectively. Normally only if I know one of them is a tracker or a related site is malfunctioning. If this is required functionality, I'd like to see the code behind it. (I know it's probably related to the "first party tracker resistance", but I'd still like to manage my own cookies)
