Blue Light Filter is a Firefox extension that reduces eye strain by applying a customizable warm color filter to web pages. Adjust the filter intensity from 10% to 90% and set an automatic schedule for nighttime use. The filter is non-intrusive, preserving page readability with blend mode. Your preferences are saved across sessions, and updates are applied in real-time without needing to reload pages. Easily install the extension via about:debugging for a more comfortable browsing experience, especially at night.
