Typing a word or words that don't look like a url or file has so far as I can recall always searched the default search engine for the word or query. This so far as I can recall has always been the case. Can you replicate this in a fresh profile to ensure this isn't just something you have set?

I run into the same thing somewhat frequently. it's the only real issue that I have with firefox. it's definitely not related to the profile, and it only seems to happen with fast enough input+enter.

it's really jarring to be sent to a random domain when looking up something in a hurry.
