| | | | |
| − | This release version (v.03.1) dynamically removes the search engine when the user navigates away from the site. If the user chooses to manually remove the search plugin from the list of installed engines, the search engine is then placed on the list of available engines as an "Add <Search Engine>" searchbar menu item. The user may now manually "Add" the available search engine as usual and it will not be dynamically removed from the list of installed engines on the searchbar list when the user navigates to another web site.

| − |
| |
| − | 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_-_localsearchpatch_v031.txt patch file] into a text file and name the file localsearchpatch_v031.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?title=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 installed engines. The newly added search engine appears as the current engine and it can be used to search the web site.
| |
| − |
| |
| − |
| |
| − | 4. Navigate to a different web site that offers a search engine plugin. Observe that the search engine that was dynamically "Added" at the previous web site is no longer on the list of installed engines but the search plugin for the current web site has been dynamically loaded and it appears as the current engine for searching the site.
| |
| − |
| |
| − |
| |
| − | 5. Open the Search Engine Manager's dialog and "Remove" the dynamically "Added" search engine. Notice that it is no longer on the list of installed engines and it is now listed as an "Add <Search Engine>" menu item. If you choose to "Add" the engine back to the list of installed engines, it will remain as an installed engine when you navigate to a different web site.
| |
| − |
| |
| − |
| |
| − | 6. Navigate to a web site that offers a search engine plugin and then to a different site that does NOT offer a search plugin. Observe that the dynamically "Added" search engine is no longer on the list of installed engines.
