About:Config Tweak
To adjust the built-in Ctrl+Enter setting, you can just set some values in the Firefox configuration to change the default from .com to whatever else you want. If you want to change Shift+Ctrl+Enter then you’ll have to skip down to the next section.
Navigate to about:config in your address bar, and then filter by browser.fixup as shown here:
There are a couple of values that you can set related to this setting:
browser. fixup. alternate. enabled – You can use this to turn the Ctrl+Enter behavior off entirely. browser. fixup. alternate. prefix – This value sets the prefix assigned before the keyword you type. browser. fixup. alternate. suffix – This value sets what is assigned after the keyword.

If you want to configure all of the settings, including the Shift+Enter for .net and the Ctrl+Shift+Enter for .org, you can use the URL Suffix extension to configure all of them, or even set a custom value for when you hit Enter in the address bar.
Install the extension, and then open up the options through the add-ons screen. You’ll see this easy to use dialog:
