Firefox : 2 different URLs for bookmarks : keyword (for as search engine) and base

Question

With a bookmark of IMDb http://www.imdb.com/find?q=%s and a keyword imdb, I can type imdb seven then enter, and it will send me at http://www.imdb.com/find?q=seven.

With the same bookmark or another one how can I make imdb then enter go to http://www.imdb.com/, and not http://www.imdb.com/find?q=?

EDIT

Thanks to iglvzx, here's a JavaScript solution (original script by iglvzx, modified to load the main URL if the bookmark is selected in Firefox's menus). m is main URL, s is search. See his answer for more information.

javascript:(function(){var q='%s',m='http://www.google.com/',s='http://www.google.com/search?q='+q;if(keywords==''||keywords=='%'+'s'){window.location=m;}else{window.location=s;}})();

Answer 1

You can achieve this with a JavaScript bookmarklet. I will post the uncompressed code first (so it's easy to read), and then the code compressed to a single line for Firefox.

Uncompressed: ^{Thanks, @Didjo, for catching the extra %s case!}

javascript:
(function(){

    var keywords = "%s";
    var mainURL = "http://superuser.com/";
    var searchURL = "http://superuser.com/search?q=" + keywords;

    if (keywords == "" || keywords == "%" + "s")
    {
        window.location = mainURL;
    }
    else
    {
        window.location = searchURL;
    }

})();

Compressed:

javascript:(function(){var keywords="%s";var mainURL="http://superuser.com/";var searchURL="http://superuser.com/search?q="+keywords;if(keywords==""||keywords=="%"+"s"){window.location=mainURL}else{window.location=searchURL}})();

Setup:

1. Create a new bookmark. Open the Firefox Library.

   

2. Select a folder. Right-click and select New Bookmark....

   

3. Enter the name, location, and keyword fields for the bookmark, pasting the JavaScript bookmarklet as the location.

   

4. Close the Library.

Demo:

Now, you can launch a location or perform a search using a single keyword!

• With search keywords:

Answer 2

Add to Search Bar does exactly what you want. For example, when you type imdb battleship it searchs for the movie battleship, but when you type imdb, it opens imdb.com.

Answer 3

You can try multiple bookmarks with different name (say prepending a letter) as discussed in the comments.

Other than that, you may want to try the instafox plugin. Combined with bookmarks, it could give you the desired result.
