Release 89.0 - How to Remove Excessive Bookmarks Padding

Hi, I'm looking for assistance in removing/restyling the large line spacing between bookmark items added in release 89.0. Operating system is Windows 10. I've tried the workaround from another forum adding a userChrome.css file to the chrome folder in my user profiles folder with the following code:

/*** Tighten up drop-down/context/popup menu spacing ***/

menupopup > menuitem, menupopup > menu {

 padding-block: 4px !important;


root {
 --arrowpanel-menuitem-padding: 4px 8px !important;


This had no effect.

Any help would be appreciated. The added padding is not helpful, but makes for unnecessary scrolling to locate bookmarks.

Thank you! :)

Workaround: 1. In Firefox, Open a tab and enter about:config, click OK after the warning 2. search for proton, a few will come up, change all the ones that are true to false. One was already false so I kept it, and the last one had a 3, which I kept. 3. Exit and open FF.

I've got things working as normal again.

Basically Check a setting in Firefox about:config Access profile,create a folder, create a file and you do not need to write code because I have supplied the text, you just copy and paste. So work through instructions step by step. Note: I have added an image below to show process. If you cannot see details, access forum and click on image to enlarge.

  • Open 'about:config'

Info at link if unsure but basically type about:config in the address text bar.

  • in search type: legacy
  • look for: toolkit.legacyUserProfileCustomizations.stylesheets
  • make sure it is set to 'True'

Whilst in about:config I search for 'proton' and found 6 items which are all set to false.

Now access the profile itself:

  • Menu app icon > Help > More Troubleshooting Information
  • About 11th in list is 'Profile Folder' - click on the 'Open Folder' button

A new window opens showing the contents of your Firefox profile.

  • Create a new folder and call it chrome - it must be spelt correctly - all lowercase.
  • Open a text editor eg: Notepad
  • Copy all the text shown between the lines below and paste it into 'Notepad'.

I advise you double check the content shown in the email you receive is the same as the info posted in this forum question.

menupopup > menuitem, menupopup > menu {
  padding-block: 3px !important;
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;

  • Exit Firefox now - you need to close the browser; this is important.

The Notepad document:

  • File > Save As
  • Choose where to save it - it must be saved in the 'chrome' folder you just created.
  • Save the Notepad file with this name: userChrome.css

All lowercase except for the 'C' which is uppercase.

  • Make sure the 'Save as Type' is 'All files' - not a text document.
  • click on 'Save'

In the 'chrome' folder, it's type will be described as 'Cascading Style sheet.

Start Firefox
