Do you mean you want the address bar at the bottom of the window? To change the position of the toolbars I believe you need a userChrome.css file. Remove the blank space in the link below.

No, I just want to move it down below the bookmarks toolbar.

You need a userChrome.css file for that as well. You will probably have to look elsewhere for code such as the Reddit sub FirefoxCSS, gitlab or mozillazine. org.

Something like this in userChrome.css should work.

#navigator-toolbox #nav-bar {
 -moz-box-ordinal-group:10 !important;
}

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.

• about:config => toolkit.legacyUserProfileCustomizations.stylesheets = true

That looks like it might work. However, I cannot find the userChrome.css file. Where is it supposed to be?

It is not that difficult to create userChrome.css if you have never used it.

The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder with the random name (xxxxxxxx.default-release).

You can find the button to go to the profile folder under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in the profile folder with the random name (name is all lowercase). In the chrome folder you need to create a plain text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted. On Mac you can use the TextEdit utility to create the userChrome.css file as a plain text file.

In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt file extension and you end up with a file named userChrome.css.txt. To avoid this you need to make sure to select "All files" in the dialog to save the file in the text editor using "Save File as".

You need to close (Quit/Exit) and restart Firefox when you create or modify the userChrome.css file.

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.

So now I'm confused. Without a direct answer to questions, everything gets disconnected.

It appears now that you are implying that one must create the file.

Yes, you have to create it in the same way as userChrome.css so look at the links which tell you how to create userChrome.css.
