Summary
I’m proposing an optional reading-direction toggle (Top→Bottom / Bottom→Top) for Firefox Reader Mode and accessibility settings. The feature reorders rendered text only (presentation layer), without changing content, semantics, or DOM structure.
Problem
Standard top-to-bottom reading increases visual strain, cognitive load, and focus decay for a meaningful subset of users—especially those with ADHD, dyslexia, visual tracking strain, or anxiety-related focus lapses.
Observation / Evidence
I conducted a pilot study with 333 global participants comparing standard reading to a bottom-to-top (“ladder”) presentation. Results showed measurable differences in perceived focus, breathing ease, and reading persistence, with strongest effects among focus-challenged readers. This is not a replacement for standard reading—only an optional toggle.
What the toggle does
Reverses display order of lines (bottom→top)
No change to text, grammar, semantics, or layout logic
User-controlled, off by default
Ideal for Reader Mode / accessibility preferences
Why Firefox
Firefox already prioritizes reader control, accessibility, and experimental UX features. This toggle fits naturally alongside font size, spacing, and contrast controls.
Request
Explore this as an experimental accessibility / Reader Mode feature. I’m happy to provide anonymized study results, mockups, or participate in UX review.
