关于这个附加组件
The Find dialog, as used by some extensions (such as ChatZilla) and by some SeaMonkey components, uses the Find service to store find settings in between uses. However after a restart the find settings get reset to internal defaults. This extension replaces the Find service with a component that stores find settings in preferences so that they are persisted across restarts. This can also be used to force find settings to default to preferred values after every restart by creating appropriate user.js entries.
