Hi, do you mean it isn't long enough? You can drag the end of it in Customize Mode to extend it - Customize Firefox controls, buttons and toolbars. Note; if you already have add-on buttons at the end of it, you will probably need to temporarily remove them to the 3-bar menu before you can drag the address bar - you can drag them back afterwards. (Right click on them > Remove from Toolbar).

You can change the appearance and font size with - for example - https://addons.mozilla.org/en-US/firefox/addon/cstbb/

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

You can consider to move the search bar to the "3-bar" menu button drop-down list via Customization mode or via the right-click context menu of the magnifier icon (Move to Menu).

You can look at this extension to adjust the font size in the user interface.

You can set a global zoom via the Options/Preferences of the extension (about:addons or the Tools menu) that modifies layout.css.devPixelsPerPx. Modifying layout.css.devPixelsPerPx affects user interface and web pages (global zoom). You can use an extension to correct the appearance of web pages.

You can use code in the userChrome.css file to set a font-family and font-size for the location/address bar and other search bars. I'm using this code to make the Add code to the userChrome.css file below the default @namespace line.


@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

/* font-size: url search find */
#urlbar *,#FindToolbar *,#search-container *{font-size:11pt!important}
#urlbar .textbox-input-box,#FindToolbar .textbox-input-box {font-size:12pt!important; font-family:"DejaVu Sans Mono"}

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

  • create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
  • use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)
  • paste the code in the userChrome.css file in the editor window
  • make sure that the userChrome.css file starts with the default @namespace line
  • make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.
    otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file

You can use this button to go to the current Firefox profile folder:


You can also consider to only show the security label when you hover the Control Center 'i' button and otherwise hide it to have more room for the URL.

/* Site Identity Button, EV: hide label */
#identity-box #identity-icon-labels {display:none}
#identity-box:hover #identity-icon-labels {display:-moz-box}
