Hi. Correct @ram1220. With the extension, there's an option to see a list of the ads that have been blocked on a site. I don't have the exact terminology because I don't have the extension on now that I have the full version, but basically it gives you a list of what was blocked, like 2 doubleclick ads, a facebook tracker and so on.
You can pre-open the filter log.
There will be displayed blocked requests, as well as information about what filter was blocked by a particular banner.
But in general, we decided not to save this information, but only display the number of blocked ads.
This facilitates the operation of your system, does not take up extra disk space and does not load RAM.
