I haven’t heard of intentional showing of the browser, but every element of the page has to be be compared to the list of thousands of ad patterns that ad blockers and their lists maintain in order to function.
This is typically fairly fast but could also be identified as slow in comparison to how long other extensions take to load/process a page. We are talking less than a second to cross-compare all page elements on any modern hardware.
