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.


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:

    font-size: 20px !important;

  • Thank you! Stupid follow-up qus: must I install Chrome to do that? (But Chromoe is part of Google, not part of FF, right?) Does Chrome grab my private info? – TheClamkinator Feb 11 '12 at 23:36

    This has nothing to do with Google Chrome. Follow the userChrome.css link in my answer for directions. – iglvzx Feb 11 '12 at 23:45
