+Mozilla ESLint Plugin
+=====================
+
+
+balanced-listeners
+------------------
+
+Checks that for every occurence of 'addEventListener' or 'on' there is an
+occurence of 'removeEventListener' or 'off' with the same event name.
+
+
+components-imports
+------------------
+
+Checks the filename of imported files e.g. ``Cu.import("some/path/Blah.jsm")``
+adds Blah to the global scope.
+
+
+import-browserjs-globals
+------------------------
+
+When included files from the main browser UI scripts will be loaded and any
+declared globals will be defined for the current file. This is mostly useful for
+browser-chrome mochitests that call browser functions.
+
+
+import-globals-from
+-------------------
+
+Parses a file for globals defined in various unique Mozilla ways.
+
+When a "import-globals-from <path>" comment is found in a file, then all globals
+from the file at <path> will be imported in the current scope. This will also
+operate recursively.
+
+This is useful for scripts that are loaded as <script> tag in a window and rely
+on each other's globals.
+
+If <path> is a relative path, then it must be relative to the file being
+checked by the rule.
+
+
+import-headjs-globals
+---------------------
+
+Import globals from head.js and from any files that were imported by
+head.js (as far as we can correctly resolve the path).
+
+The following file import patterns are supported:
+
+-  ``Services.scriptloader.loadSubScript(path)``
+-  ``loader.loadSubScript(path)``
+-  ``loadSubScript(path)``
+-  ``loadHelperScript(path)``
+-  ``import-globals-from path``
+
+If path does not exist because it is generated e.g.
+``testdir + "/somefile.js"`` we do our best to resolve it.
+
+The following patterns are supported:
+
+-  ``Cu.import("resource://devtools/client/shared/widgets/ViewHelpers.jsm");``
+-  ``loader.lazyImporter(this, "name1");``
+-  ``loader.lazyRequireGetter(this, "name2"``
+-  ``loader.lazyServiceGetter(this, "name3"``
+-  ``XPCOMUtils.defineLazyModuleGetter(this, "setNamedTimeout", ...)``
+-  ``loader.lazyGetter(this, "toolboxStrings"``
+-  ``XPCOMUtils.defineLazyGetter(this, "clipboardHelper"``
+
+
+mark-test-function-used
+-----------------------
+
+Simply marks `test` (the test method) or `run_test` as used when in mochitests
+or xpcshell tests respectively. This avoids ESLint telling us that the function
+is never called.
+
+
+no-aArgs
+--------
+
+Checks that function argument names don't start with lowercase 'a' followed by
+a capital letter. This is to prevent the use of Hungarian notation whereby the
+first letter is a prefix that indicates the type or intended use of a variable.
+
+
+no-cpows-in-tests
+-----------------
+
+This rule checks if the file is a browser mochitest and, if so, checks for
+possible CPOW usage by checking for the following strings:
+
+- "gBrowser.contentWindow"
+- "gBrowser.contentDocument"
+- "gBrowser.selectedBrowser.contentWindow"
+- "browser.contentDocument"
+- "window.content"
+- "content"
+- "content."
+
+Note: These are string matches so we will miss situations where the parent
+object is assigned to another variable e.g.::
+
+   var b = gBrowser;
+   b.content // Would not be detected as a CPOW.
+
+
+no-single-arg-cu-import
+-----------------------
+
+Rejects calls to "Cu.import" that do not supply a second argument (meaning they
+add the exported properties into global scope).
+
+
+reject-importGlobalProperties
+-----------------------------
+
+Rejects calls to ``Cu.importGlobalProperties``.  Use of this function is
+undesirable in some parts of the tree.
+
+
+reject-some-requires
+--------------------
+
+This takes an option, a regular expression.  Invocations of
+``require`` with a string literal argument are matched against this
+regexp; and if it matches, the ``require`` use is flagged.
+
+
+this-top-level-scope
+--------------------
+
+Treats top-level assignments like ``this.mumble = value`` as declaring a global.
+
+Note: These are string matches so we will miss situations where the parent
+object is assigned to another variable e.g.::
+
+   var b = gBrowser;
+   b.content // Would not be detected as a CPOW.
+
+
+var-only-at-top-level
+---------------------
+
+Marks all var declarations that are not at the top level invalid.
+
+
+Example
+=======

++-------+-----------------------+
+| Possible values for all rules |
++-------+-----------------------+
+| Value | Meaning               |

+| 0     | Deactivated           |
++-------+-----------------------+
+| 1     | Warning               |
++-------+-----------------------+
+| 2     | Error                 |
