Menu dispaly
Design Flaw is impacting adversely. All menus, bookmarks etc There is a huge excessive amount of space between all menu items in a list. That includes all the Menu bar items, File, Edit ,View, History, Bookmarks, Tools, Help and the Menu app icon. Bookmarks have huge clear blank spacing between items and is dreadful to use with all the scrolling. Scrolling is now being forced on users when it is unncessary. I need this fixed ASAP or else Firefox will be trashed! (It already is) Firefox version 91

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.
- toolkit.legacyUserProfileCustomizations.stylesheets = true
Above did not solve my problem. No changes appeared.
Did you make sure that userChrome.css is in the chrome folder (all lowercase) in the Firefox profile folder and that the file is a " Cascading Style Sheet" and not a TEXT file ?
Can you add screenshots that show the location and content of userChrome.css ?
Were you already using userChrome.css ?
userChrome.css @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;}
