Default to Firefox for browser automation and decide when Chrome is truly required. Use before any task that needs a browser: fetching a page, grabbing cookies, headless runs, logging into a site. Includes a matrix of which tasks must stay on Chromium and why. Triggers: /firefox, /ff, via firefox, need a browser, headless browser, which browser to use, browser automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /firefox — браузер по умолчанию > ## ⭐⭐ ПРИКАЗ 04.08.2026 (anton, дословно): «по максимуму использовать ЛИСУ. Через 1-2 недели ЗАМЕРИМ. Моё мнение — лиса будет МЕНЬШЕ глючить». > **Что изменилось против 30.07:** Firefox был *дефолтом с правом отойти*. Теперь он **максимум**: каждая браузерная задача едет на Лисе, пока строка §2 не запретит прямо. Раньше законным ответом было «ну тут привычнее Chrome» — теперь это не ответ. Единственный законный отход — названная строка матрицы §2. > **Окно замера: 04.08 → 18.08.2026.** Считает `browser_usage_log` (см. §7), решение по цифрам принимает Антон. До 18.08 гейт НЕ блокирует Chrome — блокирующая дверь исказила бы те самые цифры (§5.7 понарошку-сначала). > **Гипотеза Антона, которую проверяем:** «Лиса будет МЕНЬШЕ глючить». Она может и не подтвердиться — тогда честно откатываем, а не подгоняем цифры (`fake-it-courage-not-fake-numbers`). > **Правило одной строкой:** нужен браузер → берёшь Firefox. Chrome — только если строка матрицы §2 прямо говорит «вынужденно», и тогда называешь причину вслух. …

How to install
mdr add tonydzi/second-brain-starter-kit/firefox@sha256:fba6390edbb7f680The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
