Strange space above side bar since 157.0 / still in 158.0!

Please address this error and don't ignore it. Thank you.

Hi, two questions:

(1) It looks like you disabled the newer style sidebar (the one with the vertical button/launcher bar ) and are using the classic one. (In other words, in about:config, sidebar.revamp => false.)

Is that right?

(2) Do you notice the same excess spacing problem with built-in sidebars like Bookmarks and History, or only add-on sidebars?

I agree this is not a good approach, it's more likely to require some adjustments to margins or padding:

The userChrome.css 'trick' with

sidebar-header #sidebar-box { 
   display: none !important;  
}

didn't do it.

I think if this is standard for the Nova visual refresh, you'll need a new rule. If you don't find one here, try the r/FirefoxCSS subreddit (https://www.reddit.com/r/FirefoxCSS/).

Hi, thank you! :)

(1) no, unfortunately sidebar.revamp is set to true (2) yes, I do. :( please see screenshots attached.

Thank you very much for the hint with the FirefoxCSS subreddit! Will check that out! :)

Do you want to try something like this in your userChrome.css file?

  /* Remove excess space above and below sidebar name */
  #sidebar-panel-header {
    padding-block: 0 !important;
  }
  #sidebar-panel-header > h4 {
    margin-block: 0 !important;
  }
  /* Remove excess space above and below sidebar search box */
  #sidebar-search-container {
    padding-block: 0 !important;
  }
