Freebuff Ad Block

Freebuff Ad Block removes the advertising slots that appear in the freebuff.com web app, including the ones injected while a build is running, which never make a separate network request and so are invisible to a normal blocklist. It works in three layers: network rules that stop ad requests before they leave the tab, a DOM layer that clears out slots rendered mid-build, and a picker you can use to hide anything the heuristics miss. Scoped to one site. It only ever touches freebuff.com. Requests are matched only when they originate from a freebuff.com page, so it does not follow you anywhere else. Nothing leaves your browser. No accounts, no analytics, no telemetry, no remote code. The only stored data is your on/off setting and any element rules you create yourself, kept in the browser's own synced storage. It cannot break your build. A priority-100 allow rule covers freebuff.com's own traffic, so the streaming response is never matched by a block rule.
