31 // Preferences are set for automation on startup, unless
32 // remote.prefs.recommended has been set to false.
34 // Note: Clients do not always use the latest version of the application. As
35 // such backward compatibility has to be ensured at least for the last three
38 // INSTRUCTIONS TO ADD A NEW PREFERENCE
40 // Preferences for remote control and automation can be set from several entry
42 // - remote/shared/RecommendedPreferences.sys.mjs
43 // - remote/test/puppeteer/packages/browsers/src/browser-data/firefox.ts
44 // - testing/geckodriver/src/prefs.rs
45 // - testing/marionette/client/marionette_driver/geckoinstance.py
47 // The preferences in `firefox.ts`, `prefs.rs` and `geckoinstance.py`
48 // will be applied before the application starts, and should typically be used
49 // for preferences which cannot be updated during the lifetime of the application.
51 // The preferences in `RecommendedPreferences.sys.mjs` are applied after
52 // the application has started, which means that the application must apply this
53 // change dynamically and behave correctly. Note that you can also define
54 // protocol specific preferences (CDP, WebDriver, ...) which are merged with the
55 // COMMON_PREFERENCES from `RecommendedPreferences.sys.mjs`.
57 // Additionally, users relying on the Marionette Python client (ie. using
58 // geckoinstance.py) set `remote.prefs.recommended = false`. This means that
59 // preferences from `RecommendedPreferences.sys.mjs` are not applied and have to
60 // be added to the list of preferences in that Python file. Note that there are
61 // several lists of preferences, either common or specific to a given application
62 // (Firefox Desktop, Fennec, Thunderbird).
64 // Depending on how users interact with the Remote Agent, they will use different
65 // combinations of preferences. So it's important to update the preferences files
66 // so that all users have the proper preferences.
68 // When adding a new preference, follow this guide to decide where to add it:
69 // - Add the preference to `geckoinstance.py`
70 // - If the preference has to be set before startup:
71 // - Add the preference to `prefs.rs`
72 // - Add the preference `browser-data/firefox.ts` in the puppeteer folder
73 // - Create a PR to upstream the change on `browser-data/firefox.ts` to puppeteer
74 // - Otherwise, if the preference can be set after startup:
75 // - Add the preference to `RecommendedPreferences.sys.mjs`
