Firefox will not load intranet sites. It used to prepend and append www. and com to all intranet lookups.

We've got an intranet Nagios monitor site. The address is http://servnagios/nagios but each time Firefox (39.0) change automaticaly the address in http://www.servnagios.com/nagios --> of course we've got a DNS fail error : URL : GET http://www.servnagios.com/nagios Catégorie : Uncategorized URLs Motif : UNKNOWN Notification : DNS_FAIL

In IE there's no problem. Of course, Firefox use the same system proxy configuration as IE. How is it possible to setup Firefox to don't automaticaly change intranet addresses (add www. and domain .com)?

http://www.servnagios.com/nagios == Server not found

I am using Firefox 36 on Windows 7.

I tried several web search engines. Nothing found. Please verify the link. Is it in your history?

The feature of adding www. before and .com after is called fixup and you can try disabling it to see whether that helps.

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste fix and pause while the list is filtered

(3) Double-click the browser.fixup.alternate.enabled preference to switch it from true to false

Does that help?

By the way, is this is new issue in Firefox 39 or did you have the same issue in earlier versions of Firefox (or never tested it in earlier versions of Firefox)?

Hi,

I saw and change this parameter but still the same problem :( Each time i want to go to http://servnagios/nagios with Firefox, it does a redirection to http://www.servnagios.com/nagios that is no my need and of course doesn't exist.

Hmm, that fixed it for me -- in Firefox 37.

I'm trying to think of where Firefox might have stored an incorrect redirect that is bypassing normal name resolution, but nothing is coming to mind.

I'm in firefox 40 x64 right now, still the same. I tried v37 x86 and 3.6 version too, but still the same :(
