As a note, Chromium/Chrome has the same behavior.

Hello profile,

Would you do this please :

Type in the address bar   about:config   and press Enter.
(ignore the warning)

Type in the search bar and look for the preference :

keyword.enabled  and make sure its value is set to   false.

Do the same for these two preferences :

browser.fixup.alternate.enabled
and
browser.urlbar.suggest.searches

If you had to change anything, then close and restart Firefox.

Also   (just to make sure)   check your settings in the 3-bar menu :

Options <big>→</big> Search <big>→</big> Search Suggestions.

The dot in the address input makes the browser think it is an address. Call a search engine manually. Then do your search.

https://www.bing.com/search?q=127.1

https://www.google.com/search?q=127.1

https://duckduckgo.com/?q=127.1

What kind of address is http://127.1/ ?

I notice if I type

192.168

Firefox plans to send that to Google, but if I add a .1

192.168.1

then Firefox plans to visit http://192.168.0.1/

This is going to search:

100.00-99.00

while this is going to DNS:

100.0x-99.00

There seems to be some code for handling strings with only numeric digits that varies from other kinds of strings. I wonder whether this could be related to people wanting to use the "calculator" feature of Google search from the address bar?

Hi McCoy,

Thank you for your suggestions. However, changing these settings will "break" normal user behavior - like typing in keywords in the address bar for a duckduckgo search. But I agree that it will make Firefox connect to the example "127.1" instead of searching. The same applies to decimal notation, eg 2130706433.

I believe Firefox should conform to correct IP syntax, parsing valid ip adresses as such, and then connecting to the typed in address. IMO, it doesnt not make sense that it would search for eg. "127.1" instead of recognizing it as a valid IP address. (I tried finding a relevant RFC but couldnt?)

In my point of view, it looks like a logical parsing "bug" in the keyword search function?

I assumed   (which I shouldn't have)   that you didn't want to use the address bar for   any   searches,   not just in this case   (my bad .... )

Heh, well..it is in fact very helpful to be able to search for stuff - still being able to save precious keypresses :-)

Kindof on topic: I have been completely unable to find IETF/RFC material on shortening IPv4 addresses. It seems that it does not exist?

You just made me look for something I had never even heard of :   IETF/RFC.

Then I went to see if I could find that material on shortening IPv4 addresses   -   all I could find was from ages ago.

So sorry .....

Now, if only this was about IPv4 instead of IPv6 :

Then I found this add-on :

Is there a chance that it will do what you are looking for ,   or does it not even come close ?

Note that you can assign a keyword to a search engine (ddg) or type an '@' to initiate a search and select a search engine from the drop-down list (a keyword search engine that starts with a '@' is included).
