What was the name of the about:config setting?

You can add "www." and ".com" by pressing Ctrl+Enter.

With a site you have visited before, you normally would have address bar autofill:

type amazon in the address bar => default action is to visit https://www.amazon.com/

(Of course, if you do not keep history, then that may not work.)

If you were to disable address bar autofill (browser.urlbar.autoFill => false), the behavior would change:

type amazon in the address bar => default action is to send it to your default search engine

If you were to also disable address bar search (keyword.enabled => false), then Firefox would do the DNS lookup of your exact text.

Is that your configuration, more of a Firefox 1 approach without the newer behaviors?

Thanks for the replies.

I have browser.url.autofill set to true.

the pic below shows the rest of the settings, which have not changed. Before the update, with these same settings, the address bar worked as I wanted it to. After the update, with the same settings, it does not. I know that hitting Ctrl+Enter does the same thing but for years I didn't have to and was curious as to what changed.

Do other autofills work or have they all stopped working? If they all stopped working, and history wasn't cleared, maybe there is a file corruption problem. Suggestions for that:

First, if you haven't already, please do a normal shutdown and/or restart of your system. Restarting Windows can help by freeing up locked files, completing any deferred updates, and resolving temporary file permission issues.

Next, run the "Verify Integrity" diagnosis and repair function. That's here:

Open Firefox's Troubleshooting Information page using any of these methods:

• "3-bar" menu button > Help > More Troubleshooting Information
• (menu bar) Help > More Troubleshooting Information
• type or paste about:support in the address bar and press Enter

Near the bottom, there is a section titled Places Database -- that's the file which stores history and bookmarks. Click the button labeled Verify Integrity. There may be a 10-15 second delay before results appear.

If all is well, the report that appears below the button should start with:

> Task: checkIntegrity
+ The places.sqlite database is sane
+ The favicons.sqlite database is sane
> Task: invalidateCaches
+ The caches have been invalidated
> Task: checkCoherence
+ The database is coherent

Hopefully all that is fine. The table relevant to autofill is moz_origins so if it reports a problem with that one, that could be the problem. This diagnostic may clean up the problem without detecting that there is a problem, so it's good to try in any event.

Note that browser.fixup.alternate no longer works in 119. Your screenshot doesn't show the full width of the the about:config page, but this pref should have a trashcan at the far right, meaning that the pref is no longer there by default. You can click the trashcan to reset and remove this not functioning pref. browser.fixup.alternate defaults to true, i.e. you can no longer disable this feature.
