Preferences¶

This document describes Preferences affecting the toolkit Search Service. Preferences that are generated and updated by code won’t be described here.

User Exposed¶

These preferences are exposed through the Firefox UI.

browser.search.suggest.enabled (default: true): Whether search suggestions are enabled in the search bar. Turning this off also currently prevents search suggestions in the address bar.

These preferences are normally hidden, and should not be used unless you really know what you are doing.

browser.search.log (boolean, default: false): Whether search service console logging is enabled or not.
browser.search.suggest.timeout (number, default: 500): When requesting suggestions from a search server, it has this long to respond.
browser.search.update (boolean, default: true): Whether updates are enabled for OpenSearch based engines. This only applies to OpenSearch engines where their definition supplies an update url. Note that this does not affect any of: application updates, add-on updates, remote settings updates.

These preferences are experimental and not officially supported. They could be removed at any time.

browser.search.separatePrivateDefault.ui.enabled (boolean, default: false): Whether the UI is enabled for having a separate default search engine in private browsing mode.
browser.search.separatePrivateDefault (boolean, default: false): Whether the user has selected to have a separate default search engine in private browsing mode.
