Works without problem.

The webpage redirects twice:

$ curl --head http://docs.python.org/3.4 
HTTP/1.1 301 Moved Permanently
...
Location: https://docs.python.org/3.4
...

$ curl --head https://docs.python.org/3.4 
HTTP/1.1 301 Moved Permanently
...
Location: https://docs.python.org/3.4/
...

$ curl --head https://docs.python.org/3.4/
HTTP/1.1 200 OK
...

When in firefox' about:config I set

network.http.redirection-limit 1

(the original value is 20 over here) I get an "Umleitungsfehler" 
(redirection error in german). Maybe you should have a look at this setting. 
If that's not the cause -- is there any error message that firefox displays 
when you enter docs.python.org/3.4 ?
