It is submitted as scalar values along with the +normal telemetry ping. There are a number of different parts to this telemetry: + +UI Areas +-------- + +For the purposes of this telemetry a set of areas are defined: + +* In the main browser UI: + + * ``menu-bar`` - The main menu. + * ``menu-toolbar`` - The normally hidden toolbar that holds the main menu. + * ``titlebar`` - The optional title bar. + * ``tabs-bar`` - The area where tabs are displayed. + * ``bookmarks-bar`` - The bookmarks toolbar. + * ``app-menu`` - The main application (hamburger) menu. + * ``tabs-context`` - The context menu shown from right-clicking a tab. + * ``content-context`` - The context menu shown from right-clicking the web page. + * ``widget-overflow-list`` - Items that have overflowed the available space. + * ``pinned-overflow-menu`` - Items that the user has pinned to the toolbar overflow menu. + * ``pageaction-urlbar`` - Page actions buttons in the address bar. + * ``pageaction-panel`` - The page action (meatball) menu. + * ``nav-bar-start`` - The area of the navigation toolbar before the address bar. + * ``nav-bar-end`` - The area of the navigastion toolbar after the address bar. + * ``unified-extensions-area`` - The unified extensions panel. + +* In ``about:preferences`` the different cagtegories are used: + + * ``preferences-paneGeneral`` + * ``preferences-paneHome`` + * ``preferences-panePrivacy`` + * ``preferences-paneSearch`` + * ``preferences-paneSearchResults`` + * ``preferences-paneSync`` + * ``preferences-paneContainers`` + +Widget Identifiers +------------------ + +In order to uniquely identify a visual element a set of heuristics are used: + +#. If the element is one of the customizable toolbar items then that item's ID + is used. +#. If the DOM element has an ID set then that is used. +#. If the DOM element's class contains one of ``bookmark-item``, + ``tab-icon-sound`` or ``tab-close-button`` then that is used. +#. If the DOM element has a ``preference`` ``key``, ``command``, ``observes`` or + ``data-l10n-id`` attribute then that is used. +#. If there is still no identifier then this is repeated for the DOM element's + parent element. + +Widget Locations +---------------- + +The keyed scalar ``browser.ui.toolbar_widgets`` records the position of widgets in +the UI. At startup the positions of widgets are collected and recorded by +setting the scalar key ``<widget id>_pinned_<area>`` to true. The widget ID are +the IDs of the elements in the DOM. The area is one of the areas listed above +from the browser UI that can be customised. + +For the areas that can be controlled the scalar keys ``<area>_<off/on/newtab>`` are set. +``newtab`` is special to the Bookmarks Toolbar and is used when the toolbar will only +be shown on the New Tab page. + +Widget Customization +-------------------- + +The scalar ``browser.ui.customized_widgets`` records whenever the user moves a +widget around the toolbars or shows or hides some of the areas. When a change +occurs the scalar with the key ``<widget id>_<action>_<old area>_<new area>_<reason>`` +is incremented. The action can be one of ``move``, ``add`` or ``remove``. Old +area and new area are the previous and now locations of the widget. In the case +of ``add`` or ``remove`` actions one of the areas will be ``na``. For areas that +can be shown or hidden the areas will be ``off`` or ``on``. The reason is a simple +string that indicates what caused the move to happen (drag, context menu, etc.). + +UI Interactions +--------------- + +The scalars ``browser.ui.interaction.<area>`` record how often the use +interacts with the browser. The area is one of those above with the addition of +``keyboard`` for keyboard shortcuts. + +When an interaction occurs the widget's identifier is used as the key and the +scalar is incremented. If the widget is provided by an add-on then the add-on +identifier is dropped and an identifier of the form ``addonX`` is used where X +is a number. The number used is stable for a single session. Every time the user +moves or interacts with an add-on the same number is used but then the numbers +for each add-on may change after Firefox has been restarted. + +Profile Count +============= + +The scalar ``browser.engagement.profile_count`` records how many profiles have +been used by the current Firefox installation. It reports a bucketed result, +which will be 0 if there is an error. The raw value will be reported for 1-10, +but above that, it will report 10 for 10-99, 100 for 100-999, 1000 for +1000-9999, and 10000 for any values greater than that. + +The profile count data for an installation is stored in the root of the +update directory in a file called ``profile_count_<install hash>.json``. The +full path to the file will typically look something like +``C:\ProgramData\Mozilla\profile_count_5A9E6E2F272F7AA0.json``. + +This value is meant to be resilient to re-installation, so that file will not +be removed when Firefox is uninstalled. diff --git a/browser/docs/CommandLineParameters.rst b/browser/docs/CommandLineParameters.rst new file mode 100644 index 0000000000..5ba4e6df8d --- /dev/null +++ b/browser/docs/CommandLineParameters.rst @@ -0,0 +1,29 @@ +======================= +Command Line Parameters +======================= + +Firefox recognizes many (many!) command line parameters.
