OpenSearch in Firefox

I am looking for a way to add a Chrome/Chromium-like behavior to Firefox. Using Chrome you can press Tab when opening a web page using the location bar, and then search the site-specific search engine using OpenSearch. Is there a way to do that in Firefox? It should also be able to automatically add the search engines without the need for manual interaction.

Solution 1:

There are 2 possible solutions to add this functionality to Firefox.

1. Smart Keyword - Built-in Firefox functionality to define a keyword for the search function on a specific site, and execute search in the location bar using keyword search_string then pressing Enter. Steps below (modified from link).

   1. Visit the page on the target website that has the search field that you wish to set as a keyword (e.g. http://imdb.com).
   2. Right-click on the search field and select Add a Keyword for this Search....
   3. In the New Bookmark dialog, enter an appropriate name for the bookmark (e.g. "IMDB Search"), and create a keyword (e.g. "imdb" or "imdb.com").
   4. Select any bookmark folder to contain the smart keyword. Click OK.
   5. To use the created smart bookmark, open a new tab, and enter the keyword and the search string in the Location bar and then press Enter (e.g. imdb William Shatner).

2. InstantFox Quick Search Add-on - An add-on to customize search shortcuts and autocomplete while typing. Manually define a search shortcut, then execute search in the location bar using shortcut search_string then pressing Enter (e.g. imdb William Shatner). More information here.
