Small Text Big

This extension enlarges text and makes it higher contrast, so that website text is easier to read. The text size is increased inversely depending on its size. This means small sized text is made much bigger than larger text, which is slightly increased in size. All text within size of Threshold setting is increased in size with text closer to Font Threshold size increasing less than text much lower size than Threshold, depending of Font Increase % setting. Text size of ANY TEXT IS NOT DECREASED to less than its normal size. Smaller text becomes as large as (or larger than) text of Threshold size. Text near the Threshold size is unchanged or changed very slightly. Text contrast can be increased by the 'Strength' slider, with high positive values making text more black / white and negative values keeping text color unchanged.The strength slider also determines the Zoom %, with default zero strength giving 175% (1.75) zoom value.
