When the user types the word "mozilla" into the location form of any web browser window, this word is evaluated as "http://www.mozilla.com" since it could be a valid url. If he types something like "mozilla great", or any string containing a space char " ", this makes an error since Mozilla tries to evaluate an invalid url "http://www.mozilla great.com" ... A great option would be to make a search for the words "mozilla great" into your favorite search engine when the user hit "return" after any space separated words of the location.

according to comment http://bugzilla.mozilla.org/show_bug.cgi?id=58867#c8 this should work if you have Internet Keywords enabled.

You are right, the internet keywords options allmost do the work. I just would like them to use the raw search engine and to not use the Netscape integrated search site. According to http://www.mozilla.org/docs/end-user/internet-keywords.html I can use http://www.google.com/search?q=Mozilla+great&sourceid=mozilla-search instead of the default : http://search-intl.netscape.com/fr/google.tmpl?cp=clkfrsrp&charset=UTF-8&all=yes&cat=World/Fran%E7ais&search=mozilla+great&lr=lang_fr This feature is great and it would be integrated into the preference pane, after an "Advanced..." botton replacing the "More Information..." botton. The user would not have to edit his prefs.js file for this feature.

Should be duped to the "spaces should mean search" bug I think ?

some more motivation for implementing this suggestion: if you type a complex query (say, site:cs.indiana.edu forms grad) and hit return, forgetting to explicitly select a search, www.site.com comes up, and then (even though "site:cs.indiana.edu forms grad" is kept in the history) the search string cannot be usefully recovered for a search, so you have to reconstruct the query. (you can't copy and paste from the pulldown history, and if you select it, mozilla just gives you site.com again.) Alternately, if the first word of the search does not successfully find a DNS hit, the browser waits without timeout until you stop it. (In this case if you stop it you can just click search)
