+// ALL CHANGES TO THIS LIST MUST HAVE REVIEW FROM A WEBDRIVER PEER!
+//
+// Preferences are set for automation on startup, unless
+// remote.prefs.recommended has been set to false.
+//
+// Note: Clients do not always use the latest version of the application. As
+// such backward compatibility has to be ensured at least for the last three
+// releases.
+
+// INSTRUCTIONS TO ADD A NEW PREFERENCE
+//
+// Preferences for remote control and automation can be set from several entry
+// points:
+// - remote/shared/RecommendedPreferences.sys.mjs
+// - remote/test/puppeteer/packages/browsers/src/browser-data/firefox.ts
+// - testing/geckodriver/src/prefs.rs
+// - testing/marionette/client/marionette_driver/geckoinstance.py
+//
+// The preferences in `firefox.ts`, `prefs.rs` and `geckoinstance.py`
+// will be applied before the application starts, and should typically be used
+// for preferences which cannot be updated during the lifetime of the application.
+//
+// The preferences in `RecommendedPreferences.sys.mjs` are applied after
+// the application has started, which means that the application must apply this
+// change dynamically and behave correctly. Note that you can also define
+// protocol specific preferences (CDP, WebDriver, ...) which are merged with the
+// COMMON_PREFERENCES from `RecommendedPreferences.sys.mjs`.
+//
+// Additionally, users relying on the Marionette Python client (ie. using
+// geckoinstance.py) set `remote.prefs.recommended = false`. This means that
+// preferences from `RecommendedPreferences.sys.mjs` are not applied and have to
+// be added to the list of preferences in that Python file. Note that there are
+// several lists of preferences, either common or specific to a given application
+// (Firefox Desktop, Fennec, Thunderbird).
+//
+// Depending on how users interact with the Remote Agent, they will use different
+// combinations of preferences. So it's important to update the preferences files
+// so that all users have the proper preferences.
+//
+// When adding a new preference, follow this guide to decide where to add it:
+// - Add the preference to `geckoinstance.py`
+// - If the preference has to be set before startup:
+//   - Add the preference to `prefs.rs`
+//   - Add the preference `browser-data/firefox.ts` in the puppeteer folder
+//   - Create a PR to upstream the change on `browser-data/firefox.ts` to puppeteer
+// - Otherwise, if the preference can be set after startup:
+//   - Add the preference to `RecommendedPreferences.sys.mjs`
