How to Change Fonts in Bookmarks Drop Down Menus

[Sky9]

Hi,

Please do not lock my post blindly. Please read the content first. I am posting it here because the 11-year-old solution is partially helpful. The navigation path is different, which I need help with. Locking my post is not gonna help me solving the issue. Thanks.

I have Firefox Extended Support Release, 78.15.0ser (64-bit) on a MacBook Pro.
I've found this 11-year-old post/thread asking the same question. There is a solution provided by user dickvl in the link below.

Since the navigation path given by ssub to save userChrome-example is no longer applicable completely. Could anyone shed light on this?

How can I find the code given below? Thanks.

You can set them independently for the toolbar and the drop down list if you want.

Code: Select all
#personal-bookmarks toolbarbutton.bookmark-item {font-size:12px!important}
#personal-bookmarks menuitem.bookmark-item {font-size:12px!important}

Add code to userChrome.css below the @namespace line.
@namespace url("http://www.mozilla.org/keymaster/gateke ... s.only.xul"); /* only needed once */
