      description: >-
        This allows extra parameters to be set for search engines requests including,
        where calls to the suggestions API, the search engine configuration defines
        those parameters.

        The use of this field should be coordinated with the Search team.

        The field value is an array of objects with key/value fields. For example:

        [
          {"key": "google_channel_row", "value": "foo"}
        ]

        This is matched to a section in the search configuration:

        "extraParams": [
          {
            "name": "channel",
            "pref": "google_channel_row",
            "condition": "pref"
          }
        ],

        In this case, the resulting URL for the appropriate search engine would have
        `&channel=foo` added to the URL when doing searches.

        If the key is not referenced in the search configuration, then no parameter
        will be added. Only the search team can update the configuration.

        Feature gate that controls whether all aspects of the weather suggestion
        feature are exposed to the user. See also `weatherKeywords` and

        suggestion, set `weatherFeatureGate` to true, `weatherKeywords` to an
        array of full keyword strings, and `weatherKeywordsMinimumLength` to a
        non-zero integer. To disable the weather suggestion, leave out all

        settings. If neither Nimbus nor remote settings defines any keywords,

    weatherKeywordsMinimumLength:

        If defined and non-zero, the weather suggestion will be triggered by

    weatherKeywordsMinimumLengthCap:
      type: int
      description: >-
        If defined and non-zero, the user will not be able to increment the
        minimum keyword length beyond this value. e.g., if this value is 6, the
        current minimum length is 5, and the user clicks "Show less frequently",
        then the minimum length will be incremented to 6, the "Show less
        frequently" command will be hidden, and the user can continue to trigger
        the weather suggestion by typing 6 characters, but they will not be able
        to increment the minimum length any further. If this variable is absent
        or zero, Firefox will fall back to the cap defined in remote settings.
        If neither Nimbus nor remote settings defines a cap, no cap will be
        used, and the user will be able to increment the minimum length without
        any limit.
