= '''Code Modifications''' =
Prior to my code modifications, the [http://lxr.mozilla.org/seamonkey/source/browser/base/content/browser.js#2770 addEngine() function] received a reference to an anonymous JavaScript [http://lxr.mozilla.org/seamonkey/source/browser/base/content/browser.js#2758 engine object] which was passed as a parameter to the function by the [http://lxr.mozilla.org/seamonkey/source/browser/base/content/browser.js#2669 onLinkAdded() function] that created it. Then, addEngine() used an nsIBrowserSearchService object to determine if the search engine was already on the list of engines. The addEngine() function used the ''title'' property of the ''engine'' object to "get" an nsISearchEngine object with a corresponding ''name'' property. If the search engine was on the list, then it was considered to be a "hidden" engine and it was ''pushed'' onto the ''browser.hiddenEngines'' array. This array is used by the [http://lxr.mozilla.org/seamonkey/source/browser/components/search/content/search.xml search.xml] file to determine how to populate and display the search engines on the searchbar menu. If the search engine was not on the list, it was ''pushed'' onto the "non-hidden", ''browser.engines'' array. The search engine would then be displayed as an "Add <Search Engine>" item on the searchbar menu and the searchbar button's background color would be changed to blue after a call to the [http://lxr.mozilla.org/seamonkey/source/browser/base/content/browser.js#2809 updateSearchButton() function].
My code modifications alter the original addEngine() function by adding the new search plugin if is NOT on the list. The search plugin is dynamically "Added" by calling the [http://lxr.mozilla.org/seamonkey/source/browser/components/search/nsSearchService.js#2726 addEngine() function] defined in the [http://lxr.mozilla.org/seamonkey/source/browser/components/search/nsSearchService.js nsSearchService.js] file. This function completes the important step of creating a '''new''' nsISearchEngine object. It is this type of object that is required by important methods in search.xml, such as [http://lxr.mozilla.org/seamonkey/source/browser/components/search/content/search.xml#208 observe()],[http://lxr.mozilla.org/seamonkey/source/browser/components/search/content/search.xml#262 offerNewEngine()] and [http://lxr.mozilla.org/seamonkey/source/browser/components/search/content/search.xml#290 hideNewEngine()]. The remainder of the code follows the normal code paths.
= '''How to Use the Patch''' =
1. Copy and paste all of the text from the [http://zenit.senecac.on.ca/wiki/index.php/Localized_Search_in_Firefox_Search_Box#Patch_File patch file] into a text file and name the file localsearchpatch_v02.txt. Save the file to your root mozilla directory. Then, [http://zenit.senecac.on.ca/wiki/index.php/Localized_Search_in_Firefox_Search_Box#Downloading_and_applying_the_patch apply the patch and recompile] your mozilla source code as described in the release v.01 notes.
2. Start-up Firefox 3 (i.e. Minefield) and go to a [http://zenit.senecac.on.ca/wiki/index.php/Localized_Search_in_Firefox_Search_Box#Web_Site_List web site] that offers a search engine plugin.
3. Notice that the search plugin has been dynamically loaded and added to the searchbar's list of "hidden" engines. The newly added search engine appears as the current engine and it can be used to search the web site.
4. Notice also that the "Add <Search Engine>" menu item is not displayed and the searchbar's drop-down list button did not turn blue because the search plugin was dynamically loaded.
5. Open the "Manage Search Engines" dialog box and "Remove" the dynamically loaded search engine. It will now appear on the the searchbar's list as an "Add <Search Engine>" menu item. It can then be added back as normal to the searchbar's list.
6. Clicking Firefox's reload button will reload the web page and trigger the code for the search plugin to be dynamically added to the list if it is not already on the searchbar's list of "hidden" engines.
