Increase size of font in bookmarks toolbar

I would like to increase the size of the font used in the bookmarks toolbar.

Can someone please help me?



  • This is not possible with browser addons as they only have restricted power and can't change the browser UI, only webcontent.

    You need to use userChrome.css to achieve that.

  • I have a userChrome.css. I need more info to accomplish my request.
  • You mentioned the Bookmarks Toolbar but your screenshot seems to show the Bookmarks Menu that drops from the top menu bar.

    On Windows, the top menu bar is under Firefox's full control, but I don't know about Linux.
