FF Font Super Enhancer от tfitfi20

FF Font Super Enhancer is an add-on to increase the readability of texts in Firefox, especially in those websites which use thin fonts.
For many users, the Firefox browser renders these fonts too lightly, and in some case they're very difficult to read.
This add-on has an intelligent function that calculates the exact amount of darkness to apply to characters (based on their color and luminance), which results in a perfect rendition.
