You can inspect details of the most recent raw HTTP requests which have been made by a web page (see below).
This is mostly useful to advanced users who want to investigate exactly what a web page has been doing. But logging these HTTP requests requires memory, and if you don't care about this technical information, then memory is being wasted.
Hence this field which lets you adjust the maximum number of the most recent HTTP requests which are to be logged for further inspection.
Enter “0” to turn off detailed logging (and consequently reduce the memory footprint of uMatrix).
Blacklisted cookies are not prevented by uMatrix from entering your browser. However they are prevented from leaving your browser, which is what really matters. Not blocking cookies before they enter your browser gives you the opportunity to be informed that a site tried to use cookies, and furthermore to inspect their contents if you wish.
Once these blacklisted cookies have been accounted for by uMatrix, they can be removed from your browser if you wish so.
Important note: Extensions can make web requests during the course of their normal operation. These requests can result in cookies being created in the browser. If the hostname from where a cookie originate is not whitelisted, the cookie will be removed from the browser by uMatrix if this option is checked. So be sure that the hostname(s) with which an extension communicate is whitelisted.

Except that this might not be happening in some browsers. Also, to some, having to close the browser in order for the session cookies to clear might not be early enough.

A few of these tricks rely[1, 2] on the browser cache, which content is often long lasting since rarely will users take the time to regularly clear their browser cache.
There is little inconvenience to clear the browser cache regularly (likelihood is that you won't notice when it happens), and the benefit is to prevent these obnoxious trackers from invading your privacy.
Check this option to have uMatrix do it for you, at the interval you wish.
