Searching Google via the Firefox Address Bar
Looking to change the default behavior of the Firefox address bar (ie. when it conducts searches)? Right now, if you mistype a web address, it tried to find the website you were looking for, similar to Google's "I'm feeling lucky" feature. The problem is, that's not very useful for most people - as what are the odds it's going to find it? Think about how many times you actually use the Google "I'm feeling luck" button.
Changing Firefox Address Bar's Default Behavior
Competing search engines tend to send queries or mistypes in the address bar directly to your default search engine. This seems like a more intuitive approach than randomly guessing at a website. To change the default behavior of the Firefox address bar so that it uses a search engine to search, you can do the following:
Voila :) you should now be able to enter anything in the Firefox address bar, it doesn't have to be a web address, and a search will be conducted using your search engine of choice. What this means is you won't have to browse to your search engine, for example google.com, each type you want to enter a search query. Quite the time saver, believe me.
