the find component shouldn't be an appshell component, so it doesn't need to be loaded at startup.

/*----------------------------- nsIFindComponent -------------------------------
| This file describes the interface for Mozilla's pluggable "find" component |
| that provides the implementation of the browser's "find in document" |
| function (and perhaps will be generalized to support similar searching in |
| other contexts). |
| |
| The component itself is a singleton (one per executing application). To |
| handle searching on a per-document basis, this interface supplies a |
| CreateContext() function that creates a search context (generally, on a |
| per document, and thus per-browser-window, basis). |
| |
| The component itself will "remember" the last string searched (via any |
| context). This way, a search in a new context (browser window) will be |
| able to search for the same string (by default). |
| |
| Clients (e.g., the browser window object) will generally use this interface |
| in this manner: |
| 1. Hold a reference to the singleton "find component". |
| 2. On initial search, ask that component to create a search "context." |
| 3. Reset the context whenever the underlying web shell changes (but since |
| a browser will usually reuse a single web shell, this won't be of |
| concern except in obscure cases). |
| 4. Forward "find" and "find next" requests to the component, along |
| with the appropriate search context object. |
| 5. Release() the search context object and the find component when the |
| browser window closes. |
