It appears that your have AutoComplete disabled, so this isn't the problem of Firefox "autofilling" that URL in the address bar before you press Enter.

If you open the web console (Ctrl+Shift+k), you should be able to see whether Firefox requests the correct URL first and gets redirected.

Does it make any difference if you include the protocol: http://192.168.0.1/

By the way, do Firefox and IE use the same proxy settings? You can view Firefox's here:

orange Firefox button (or Tools menu) > Options > Advanced > "Network" mini-tab > "Settings" button

The default is "Use system proxy settings".

Wow, quick reply. Thanks for the effort.

I type "http://192.168.0.1/" in the address bar and hit enter.

Web console says, "get http://192.168.0.1:443/" and address bar immediately flips to "192.168.0.1:443"

The proxy settings were originally set to "Use system proxy settings" and it did the same thing so I changed to "No proxy" and get the exact same result. I just tried setting it back to "Use system proxy settings" and it makes no difference.

I should also point out that FF doesn't append the ":443" until I hit the "enter" key, not before then.

I also discovered that Chrome is behaving the same way as Firefox. I can't convince either one that it's not a :443 address. Ha! I'll try forcing :80 tonight and see what happens (unless someone stumbles upon the real solution).

Is this a system setting that M$ IE is ignoring and it's the browser that's actually misbehaving in an insecure way?

I like the idea of trying :80 after the address. Nothing else is coming to mind, but if you search around with your brand of router for anything about this kind of reconfiguration, perhaps there is some other advice out there on the web.

Maybe the router is sending some response headers that make Firefox switch to that port.

I'm not sure if Live Http Headers would cache this.

If you have problem with this IP address you can read this article for all information : www.19216811ip.net

This probably isn't applicable to a router, but I'll mention it just in case: if a server ever sends a header specifying strict transport security, Firefox will remember that and always try a secure connection. That turned out to be the issue in this thread: Firefix 25.0.1 forces SSL even when http:// is specified in the location bar.

When you try to login with 192.168.o.1 or any other IP make sure to type it in the address bar, not in the search bar in your browser. In rare occasions, people do this, so take care.

This is my first post on this forum.

All the best.

If you have history items for http://192.168.0.1:443 or https://192.168.0.1 then you can try to use "Forget About This Site".

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make a note of those passwords and bookmarks.

You can't recover from this 'forget' unless you have a backup of the involved files.

It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.
