Disable Firefox "Expanding/Enlarged" URL Bar

Hello Mozilla Support, please advise on how to permanently disable the "expanding/enlarging" URL bar that continues to be featured with each new browser update. From previous experience, I have uninstalled/reinstalled and attempted to change the following advanced settings as seen on other threads:

Method 1: 1. about:config 2. browser.urlbar.openViewOnFocus = FALSE 3. browser.urlbar.update1 = FALSE 4. browser.urlbar.update1.interventions = FALSE 5. browser.urlbar.update1.searchTips = FALSE

Method 2: 1. about:config 2. browser.urlbar.disableExtendForTests = TRUE 3. browser.urlbar.maxRichResults = 0

Neither of these methods currently seem to work and even when they have worked in the past, why does Mozilla continue to enable this feature with each new update without a simple option to disable when so many users have requested instructions on how to shut off? What is the purpose of the expanding URL bar? What does an enlarged URL bar do to benefit the search experience? Is there another reason why Mozilla keeps this feature going for every new update? It often becomes time consuming to search and figure out what the new procedure is to keep disabling, every single time an update occurs.

Please help, Thank you!

There is no option to completely disable the enlargement. The options are the same for Firefox 78-84. I have a summary on my site here:

Firefox 63+ has support for "@media (prefers-reduced-motion)" to honor system settings to minimize the amount of non-essential motion.

You can create a new Number pref named ui.prefersReducedMotion on the about:config page to show or block some animations. In Firefox 78+ this includes the location bar breakout. In Firefox 80+ this replaces the tab loading indicator with an hourglass.

  • set the value to 1 if you want to block animations
    ui.prefersReducedMotion = 1
  • set its value to 0 if you want to see animations
    ui.prefersReducedMotion = 0

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
