Is the database of websites installed locally in the extension or is it calling home for every website I visit?
all three filter lists are fetched once and kept in memory when the extension is initialized (from what i can tell this happens when the browser starts), and then that local copy is used to match URLs.
For reference, the source file is background.js
URLs at the top, init calls at the bottom, and above that the event registering stuff (tab nav and nav).
Looks like the block list itself is maintained here
