Created July 27, 2018 21:06
Usage of "contexts" in the contextMenus / menus API in public add-ons at addons.mozilla.org
$ ### This is a rough estimate of the values of the "contexts" array in extensions,
$ ### presumably used as values in the contextMenus/menus.create/update API.
$ ### First, we check whether the number of reported occurrences is significant,
$ ### by checking the number of "contexts:" strings that are not followed by an array.
$ ### As the first checks show, only 10% of the matches are not arrays,
$ ### (so they are variables, expressions or not part of the menus API).
$ ### The other 90% are arrays, and significant.
$ ### LIMITATIONS

Tutorial to walk through the creation of a Git repository for Firefox/Gecko development, initialized from a git bundle.

The git-cinnabar wiki explains how to set up a repository for Firefox development in Mozilla: A git workflow for Gecko development. The first step of that tutorial, git clone hg::https://hg.mozilla.org/mozilla-unified gecko may fail if your internet connection is unreliable. Mercurial Bundles are an alternative but take 3 hours to initialize. Git bundles for Mozilla development are also available and a recommended alternative.

This tutorial walks you through the creation of a gecko repository for Firefox/Gecko development, initialized using a Git Bundle. Commands are shown on the lines starting with $, and the output is shown for reference. You can copy and paste the command in the shell.

You need at least 10 GB of free disk space for this. On October 22nd, 2020: 3.2GB for the bundle, 7GB for the repository, and a bit more f
