… takes you straight to a website.
Without my brain being switched on I typed these two words into the url bar
“bbc iplayer”
No www, no http, no .com or anything. just two words. It took me straight to the bbc iplayer website. I have never visited it before on this computer so it’s not pulling it from memory.
I guess what it’s doing is secretly doing a search for those two words and then giving me the top item on the list of founds.
I believe Firefox queries Google and takes you to the website you would have reached by clicking “I’m Feeling Lucky.” An initial check confirms this with you bbc iplayer example.
It uses some heuristic algorithm which takes you to the I’m feeling lucky if it’s obvious what the result should be or a google search page if it’s ambiguous.
If you watch the bottom left corner of firefox where it shows what sites it is connecting to (it probably says “done” right now), google.com is the first site it shows when you do that, then it changes to bbc.
If you don’t like Firefox doing that, you can change it.
Use about:config and change browser.urlbar.richResults from the default True to False, and it will just do a normal search and display the results on the Google page.
