I've tried trouble-shooting this issue myself, but I'm finding it difficult to describe my exact issue. One of my favorite features of Firefox, includes the ability to use the address bar as a search bar with my chosen search engine. However, lately whenever I try to enter searches into the address, bar, they are automatically turned into urls having "http://" added to the beginning of the search, and leaving me with a blank page. For example , the search "grapes" would yield "http://grapes/". Oddly though, when my search includes one or more terms, it seems to work perfectly normal, so it seems that it's isolated to single-worded search entries. I've read a few posts regarding the use of about:config, although they were not specific enough to help me determine if it pertained to my particular issue. Any help that could be offered would be great.
