The problem occur when searching for a *single word* using the location
bar and the proxy settings are "Manual proxy configuration". Firefox
doesn't perform a fulltext search, but redirects directly to
http://<entered word>.

Reproducible: Always

Steps to Reproduce:
1. Install a proxy server e.g. to localhost:8080
2. Change Firefox proxy settings to Manual proxy configuration and enter HTTP proxy: localhost and port:8080
3. Enter a single word into the location bar and hit enter
Actual Results: 
Firefox doesn't perform a fulltext search, but redirects directly to http://<entered word>.

Expected Results:  
Fulltext search for entered word.

When multiple words is entered search works fine. The exactly same
problem has been descibed here

Confirmed as recently as 8.0beta3 and 7.0.1 release. Fully reproducible
with the steps mentioned above.

Tested in Windows XP, but as far as I know, this is architecture
independent, and has to do with the way Firefox works when you use a
single word in the URL bar, i.e.: word

- Firefox will try to download it the http://word URL:

GET / HTTP/1.1
Host: word

- if it doesn't work (e.g. it won't resolve to a local hostname or an IP
address), it will result in a search.

Problem: when there's a proxy, the proxy answers the query with an error
page. Instead of the 504 error page (gateway timeout), it uses a 403
error (forbidden). Since that is a final error, Firefox no longer tries,
and search is never invoked.

e.g. full interchange (with nonrelevant headers edited out)

GET http://word/ HTTP/1.1
Host: word
User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:8.0) Gecko/20100101 Firefox/8.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
DNT: 1
Proxy-Connection: keep-alive
Cache-Control: max-age=0

HTTP/1.1 403 Forbidden
Content-Length: 456
<html><head><title>504 DNS look up failed</title></head><body><table width="100%"><tr><td bgcolor=#3300cc align="center" colspan=2>504 DNS look up failed</td></tr></table> The webserver for http://word reported that an error occurred while trying to access the website. Please click <a href="javascript:history.back()">here</a> to return to the previous page. <hr></body></html>

i.e. even if the proxy's error page says it's a 504 error, the actual
error code returned is 403 ("Forbidden"), so Firefox does the right
thing and doesn't do anything else.

It's the proxy's fault, but it's still very annoying and I wonder if
there could be a way for Firefox to handle this more gracefully.

Any chance someone's working on it?

Yes and pretty annoying.

Temporary workaround: if you put the single word in quotes, it does the
search instead of asking the proxy.
