The top level keys of the -ping: - -- ``locale`` - string locale of the Firefox build -- ``tiles`` - array of tiles ping objects - -An additional key at the top level indicates which action triggered the ping. -The value associated to the action key is the 0-based index into the tiles array -of which tile triggered the action.

They count the number of times certain -events happen. No timing or other correlating information is stored - purely the number of times -things happen. - -``countableEvents`` contains a list of buckets as its properties. A bucket represents the state the browser was in when these events occurred, such as currently running an interactive tour. There are 3 types of buckets: - -- ``__DEFAULT__`` - No bucket, for times when the browser is not in any special state. -- ``bucket_`` - Normal buckets, for when the browser is in a special state. The ```` in the bucket ID is the name associated with the bucket and may be further broken down into parts by the ``|`` character. -- ``bucket_|`` - Expiring buckets, which are similar to a countdown timer. The ```` in the bucket ID describes the time interval the recorded event happened in. The intervals are ``1m`` (one minute), ``3m`` (three minutes), ``10m`` (ten minutes), and ``1h`` (one hour). After one hour, the ``__DEFAULT__`` bucket is automatically used again. - -Each bucket is an object with the following properties: - -- ``click-builtin-item`` is an object tracking clicks on builtin customizable toolbar items, keyed - off the item IDs, with an object for each item with keys ``left``, ``middle`` and ``right`` each - storing a number indicating how often the respective type of click has happened. -- ``click-menu-button`` is the same, except the item ID is always 'button'. -- ``click-bookmarks-bar`` is the same, with the item IDs being replaced by either ``container`` for - clicks on bookmark or livemark folders, and ``item`` for individual bookmarks. -- ``click-menubar`` is similar, with the item IDs being replaced by one of ``menu``, ``menuitem`` - or ``other``, depending on the kind of item clicked. Note that this is not tracked on OS X, where - we can't listen for these events because of the global menubar. -- ``click-bookmarks-menu-button`` is also similar, with the item IDs being replaced by: - - - ``menu`` for clicks on the 'menu' part of the item; - - ``add`` for clicks that add a bookmark; - - ``edit`` for clicks that open the panel to edit an existing bookmark; - - ``in-panel`` for clicks when the button is in the menu panel, and clicking it does none of the - above; -- ``customize`` tracks different types of customization events without the ``left``, ``middle`` and - ``right`` distinctions. The different events are the following, with each storing a count of the - number of times they occurred: - - - ``start`` counts the number of times the user starts customizing; - - ``add`` counts the number of times an item is added somewhere from the palette; - - ``move`` counts the number of times an item is moved somewhere else (but not to the palette); - - ``remove`` counts the number of times an item is removed to the palette; - - ``reset`` counts the number of times the 'restore defaults' button is used; -- ``search`` is an object tracking searches of various types, keyed off the search - location, storing a number indicating how often the respective type of search - has happened. - - - There are also two special keys that mean slightly different things. - - - ``urlbar-keyword`` records searches that would have been an invalid-protocol - error, but are now keyword searches. They are also counted in the ``urlbar`` - keyword (along with all the other urlbar searches). - - ``selection`` searches records selections of search suggestions. They include - the source, the index of the selection, and the kind of selection (mouse or - enter key). Selection searches are also counted in their sources. - - - -``UITour`` -========== - -The UITour API provides ways for pages on trusted domains to safely interact with the browser UI and request it to perform actions such as opening menus and showing highlights over the browser chrome - for the purposes of interactive tours. We track some usage of this API via the ``UITour`` object in the UI Telemetry output. - -Each page is able to register itself with an identifier, a ``Page ID``. A list of Page IDs that have been seen over the last 8 weeks is available via ``seenPageIDs``. - -Page IDs are also used to identify buckets for :ref:`UITelemetry_countableEvents`, in the following circumstances: - -- The current tab is a tour page. This will be a normal bucket with the name ``UITour|``, where ```` is the page's registered ID. This will result in bucket IDs such as ``bucket_UITour|australis-tour``. -- A tour tab is open but another tab is active. This will be an expiring bucket with the name ``UITour||inactive``. This will result in bucket IDs such as ``bucket_UITour|australis-tour|inactive|1m``. -- A tour tab has recently been open but has been closed. This will be an expiring bucket with the name ``UITour||closed``. This will result in bucket IDs such as ``bucket_UITour|australis-tour|closed|10m``. - - - -``contextmenu`` -=============== - -We track context menu interactions to figure out which ones are most often used and/or how -effective they are. In the ``contextmenu`` object, we first store things per-bucket. Next, we -divide the following different context menu situations: - -- ``selection`` if there is content on the page that's selected on which the user clicks; -- ``link`` if the user opened the context menu for a link -- ``image-link`` if the user opened the context menu on an image or canvas that's a link; -- ``image`` if the user opened the context menu on an image (that isn't a link); -- ``canvas`` if the user opened the context menu on a canvas (that isn't a link); -- ``media`` if the user opened the context menu on an HTML video or audio element; -- ``input`` if the user opened the context menu on a text input element; -- ``other`` for all other openings of the content menu; - -Each of these objects (if they exist) then gets a "withcustom" and/or a "withoutcustom" property -for context menus opened with custom page-created items and without them, and each of those -properties holds an object with IDs corresponding to a count of how often an item with that ID was -activated in the context menu. Only builtin context menu items are tracked, and besides those items -there are four special items which get counts: - -- ``close-without-interaction`` is incremented when the user closes the context menu without interacting with it; -- ``custom-page-item`` is incremented when the user clicks an item that was created by the page; -- ``unknown`` is incremented when an item without an ID was clicked; -- ``other-item`` is incremented when an add-on-provided menuitem is clicked. diff --git a/application/basilisk/docs/index.rst b/application/basilisk/docs/index.rst deleted file mode 100644 index bfdd78e04b..0000000000 --- a/application/basilisk/docs/index.rst +++ /dev/null @@ -1,12 +0,0 @@ -======= -Firefox -======= - -This is the nascent documentation of the Firefox front-end code. - -.. toctree:: - :maxdepth: 1 - - DirectoryLinksProvider - UITelemetry - BrowserUsageTelemetry diff --git a/application/basilisk/extensions/pdfjs/README.basilisk b/application/basilisk/extensions/pdfjs/README.basilisk new file mode 100644 index 0000000000..0c67c31c06 --- /dev/null +++ b/application/basilisk/extensions/pdfjs/README.basilisk @@ -0,0 +1,7 @@ +This is a port of IsaacSchemm's PDF.JS for SeaMonkey addon, https://github.com/IsaacSchemm/pdf.js-seamonkey + +Current extension version is: 2.3.235 + +Taken from https://github.com/IsaacSchemm/pdf.js-seamonkey/releases/tag/v2.3.235 + +PdfJs.jsm ported from Firefox 60.9.0's version of PDF.js diff --git a/application/basilisk/extensions/pdfjs/README.mozilla b/application/basilisk/extensions/pdfjs/README.mozilla deleted file mode 100644 index 884f85eb38..0000000000 --- a/application/basilisk/extensions/pdfjs/README.mozilla +++ /dev/null @@ -1,3 +0,0 @@ -This is the pdf.js project output, https://github.com/mozilla/pdf.js - -Current extension version is: 1.6.315 diff --git a/application/basilisk/extensions/pdfjs/content/PdfJs.jsm b/application/basilisk/extensions/pdfjs/content/PdfJs.jsm index 7dc01c3988..7d757ea930 100644 --- a/application/basilisk/extensions/pdfjs/content/PdfJs.jsm +++ b/application/basilisk/extensions/pdfjs/content/PdfJs.jsm @@ -12,87 +12,109 @@ * See the License for the specific language governing permissions and * limitations under the License. */ -/* jshint esnext:true */ -/* globals Components, Services, XPCOMUtils, PdfjsChromeUtils, - PdfjsContentUtils, PdfStreamConverter */ -'use strict';
