Bromite AdBlock engine
Since v77 Bromite uses Chromium subresource filter with the full filter lists mentioned in the README.
The Bromite AdBlock Update Service checks at startup (after 5 seconds) and periodically (every 2 weeks) if new Bromite filters are published; if no new filters are available (checked via
Last-Modified header) then update is skipped.
Original Bromite AdBlock engine
The ad-blocking engine of Bromite till v76 was an improved version of the original engine of NoChromo, which is a very simple ad-blocking engine if compared to the others available.
This engine is still used for the SystemWebView.
