When µBlock launches, it loads all selected filter lists, parse the content, eliminate duplicates, than instantiates the filters using efficient internal representation. This parsing of the filter lists requires a good amount of temporary memory.
When µBlock launches, it loads all selected filter lists, parse the content, eliminate duplicates, then instantiates the filters using efficient internal representation. This parsing of the filter lists requires a good amount of temporary memory.
So if you look at the task manager **right after** µBlock has loaded and parsed the filters, you will still see µBlock's memory footprint as a result of loading all the filter lists. Still, at this point all this temporary memory has been relinquished to the browser, but the browser hasn't yet claimed the freed memory to make it available for reuse.
