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 µMatrix).
Blacklisted cookies are not prevented by µMatrix 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 µMatrix, 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 µMatrix 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 when using a Chromium-based browser. Also, to some, having to close the browser in order for the session cookies to clear might not be early enough.

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 µMatrix do it for you, at the interval you wish.

From Wikipedia: “HTTP referer is an HTTP header field that identifies the address of the webpage that linked to the resource being requested. ... Because referer information can violate privacy, some web browsers allow the user to disable the sending of referer information.”
If this setting is checked, µMatrix will remove the HTTP referer information if both of the following conditions are true:
Hyperlink auditing is a mechanism which allow a party, any party, to be informed about which link a user clicked on a particular web page. It is essentially a tracking feature: it allows a web site, or any third-party to that web site, to be informed about which link you clicked on which one of its web pages. The sole purpose is to track your browsing activity.

Click the extension icon while viewing this page to get started. Required reading: Behind-the-scene requests.
Beware! Blocking behind-the-scene net requests is potentially causing an issue when the user wants to install an extension from the Chrome store (including maybe preventing extensions from being updated), hence the ability to disable the feature here. Blocking can also cause other installed extensions to not work properly (those querying for remote data).
Even if this feature is not enabled, behind-the-scene requests are still logged by µMatrix. You can inspect these requests on the Statistics page.
