Answer:
The UserWay widget uses the CSS zoom property to scale elements and improve accessibility. This works reliably in many browsers. However, Firefox does not support the zoom property, which leads to different behavior.
To maintain accessibility in Firefox, the widget uses increased font size as an alternative. This can affect multiple layout elements since font scaling has broader visual impact compared to zoom.
✅ Browsers that support the CSS zoom property:
Google Chrome – fully supports
zoomSafari (macOS & iOS) – supported since version 4
Microsoft Edge (Chromium-based) – full support inherited from Chromium
Opera – full support
Brave – Chromium-based, inherits support
Samsung Internet – Chromium-based, supports
zoom
❌ Browsers that do not support the CSS zoom property:
Mozilla Firefox – explicitly does not support
zoomTor Browser – built on Firefox, also does not support
LibreWolf – a Firefox fork, same limitation
Basilisk – Firefox-based, no
