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).
Strict\nblocking,\nintroduced in version 0.3.6,\nmeans that even\nif you whitelist a specific hostname, blacklisted type of requests (plugins,\nframes, etc.) will remain blacklisted. For some users this maybe\ntoo bothersome, hence this switch.
\nStrict blocking on: blacklisted types of request (if any)\nfor a whitelisted hostname are blocked (unless you explicitly whitelist\nspecifically these types of request for the whitelisted hostname.)
\nStrict blocking off: blacklisted types of request (if any)\nfor a whitelisted hostname are allowed (unless you explicitly blacklist\nspecifically these types of request for the whitelisted hostname.)

There are many advantages to using domain- or site-scoped rules, one of them being the sandboxing of rules, a good habit for enhanced security.
For example, should you want to whitelist “all” for a web site (www.example.com), using a domain-level scope will limit this extremely permissive rule to only pages on that specific domain (example.com), while if used in the global scope (“∗”) the extremely permissive rule would apply to all pages on all web sites, i.e. the whitelisting of the whole internet.

If you use this feature, I advise that you at least blacklist frame requests and turn on strict blocking.
