How To Enable Inline Address Completion in Firefox

Firefox has an incredible amount of settings that can be changed, but only a few of them are available in the Tools>Options menu. For example, when you start typing an address that you already visited, Firefox shows a popup menu with all the URLs that match what you are writing in the address bar, but what about setting it to also complete these addresses automatically?


As you can see in the screenshot above, if you want to reach a certain address, you have to use the down arrow, or type it entirely. Let's see how can we change this...

- First of all, you have to type "about:config" in the address bar, and then press Enter.


- In the Filter field, enter "browser.urlbar.autoFill" to show only what we need...


- Double click the field highlighted in the screenshot above. As you can see below, now its value is "true", so inline completion is enabled.


- Now simply start typing an URL and notice the change!


To get back to the default settings, simply repeat all the steps above, there's nothing easier, but I hope you'll consider this useful and it's going to work well(it may be possible for some people to have a conflict between some extension and this setting, but for me, this works just great!).
