What I want to do exctly on my Mac Air 2017 is increase the tiny font on the Firefox bookmarks toolbar. The size of the toolbar is ok.. I only want to increse the font on the bookmarks themselves. I tried the PixelsPer thing in CSS and that doesnt fix it. THere must be another CSS setting that does it or how can I create one? I have created the chrome file and put the css file into it and its on my Desktop ready to go.How do I do this??It must be a Fox thing cause the bookmarks toolbar is a Fox thing,no??
