feat(theseus): Shield — tracker and ad blocking as a bundled add-on Theseus had no content blocking at all. Shield blocks requests to known tracking and advertising hosts on every site, using EasyList and EasyPrivacy through Ghostery's adblocker engine (the matcher those lists are written for). The lists ship inside the add-on so blocking works from the first launch, offline; the compiled engine is cached under the add-on's data dir (a 22 ms load instead of a 500 ms parse), and the lists refresh from their publishers about once a day. The panel shows what was stopped on the current page, a one-click allow for the site, the global switch, the running total and the rule versions with an "Update now". Network filters only for now: a blocked request never leaves the browser, but leftover empty ad boxes are not hidden yet. Host side: a "request-filter" capability. Chromium allows one onBeforeRequest listener per session, so main owns it and consults the add-ons' filters; a top-level navigation is never blocked, only http(s) subresources are offered. api.tabs (active tab and a change event) lets the panel show per-site numbers without seeing page content. 2026-09-27 19:43:14 +02:00			`{`
