Firefox- How to change font size of items in bookmarks sidebar

bookmarksfirefoxfontssidebar

In Windows. (I know I can open Desktop > Properties > Appearance > Advanced > [and figure out which item determines it; probably Menu]. But, I don't want other things changed – just the bookmarks. This is because I have so many and I want more of them to display.

I did see the question on changing font size of items in folder, on bookmarks toolbar, and sub-folders, etc; But, I'm talking sidebar on firefox, I don't have Google Chrome and I am not a developer.

Best Answer

The selector for the items in the Bookmarks Sidebar is #bookmarks-view. So, for example, adding the following rule in your userChrome.css will change the font size to 20px:

#bookmarks-view
{
    font-size: 20px !important;
}
