Probably you haven’t known that before, but Firefox Address bar has a default action to search Google using I’m Feeling Lucky sort of feature if you only type words in the address bar rather than valid url. Example is, type in your Firefox address bar “monkey island” and hit enter.

Since this is not a valid URL, instead of giving 404 Page Not Found, Firefox will send the query to the default Google Search which will search the term, and try to guess the best result “World of Monkey Island” in this case. If it can’t guess the site, it will take you to the results page, as when you search blogallalong. It still not obvious to Google what you are trying to reach ofcourse. Google must base it’s guess on large number of queries and it won’t work well for small sites. I think famous names that have multiple sites also might face problem with this as searching for Mercedes took me to the search results.
So why this is behavior, and can I modify it? It is a parameter set in Firefox, and yes ofcourse you can change it. Welcome to the open source world :). To do so, type in the Address Bar “about:config” and hit Enter. You will go to the parameter configuration page for Firefox. Now search for “keyword.url”. Update the Value to whatever you want (if you like). For example, you can force the search to be on Google normal search not the I’m Feeling Lucky one by changing the value to:
http://www.google.com/search?q=
