See bug 131540, I think you have some DNS issues with your provider, can you try with another DNS servers ?

I don't see how I can have DNS "issues" with my ISP when I am experiencing absolutely no problems with any other of the three browsers I have available. I also don't see how a DNS issue could possibly explain the fault I reported in this bug report ... how could a bad DNS lookup result in that completely invalid URL? It looks to me a case of a buffer not being cleared before a strcat operation.

Okay, I've been doing some more experiments and I think it may be related to proxying. I use Junkbuster, have done for a long time, and my setup works for both IE5 and Opera. I seem to be experiencing these apparent DNS-type problems more when I have enabled proxying than when using a direct connection. I searched bugzilla for "proxy" and found many reports though none seem to be immediate candidates.

I don't use Junkbuster, but judging the number of bug reports where Junkbuster is involved, it's not mozilla's fault, Junkbuster is buggy (broken). workaround: please set edit/preferences/debug/networking/Http Version: 1.0. See http://bugzilla.mozilla.org/duplicates.cgi (Then Find 'junkbuster'). Propose to mark dupe of bug 38488.

duping junkbuster is broken for all Http/1.1 clients as mozilla IE use only Http/1.0 for Proxies NS4.7x use always Http/1.0 ... Please select Http/1.0 in preferences/debug/networking and clear all Mozilla caches *** This bug has been marked as a duplicate of 38488 ***

Verified dupe.
