How to reduce excess spacing between lines in drop-down menus like bookmarks and right-click

Is there a way to return to the more slimmed-down tabs and menus design of before? Because the latest update has all my menus double-spaced, and they're so bloated now that it's really hard to find anything with half the information spread out to take double the space.

To fix this, I have tried other users' suggestions of disabling proton, which had worked previously but no longer seems to have any effect as of the latest update. I have also tried the "compact menus" workaround, but that doesn't affect the double-spacing within the drop-down menus themselves.

In Firefox 91+ you can no longer disable Proton and revert changes that come with this design via "browser.proton.enabled = false" on the about:config page. Best in Firefox 91+ is to set browser.proton.enabled at its default value true as the false setting can cause issues.

In Firefox 91+ you need to use code in userChrome.css to override changes coming with the Proton design.


You can use code in userChrome.css to modify the menu spacing.

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 */

menupopup > menuitem, menupopup > menu {padding-top: 2px !important; padding-bottom: 2px !important;}
*|*:root {--arrowpanel-menuitem-padding: 2px 8px !important;}

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.

You can find this button 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 this folder (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.
