+Custom fonts cause flashing text in Firefox. To amend this, tabi loads a subset of glyphs for the header. Since this (slightly) increases the initial load time, it's a good idea to try and minimise the size of this subset, or disable it completely if you're not using a custom font in your skin.
 
-You can create a custom subset tailored to your site, save it as `static/custom_subset.css`, and have it load with `custom_subset = true`.
