Right Zoom by GL Soft

Right Zoom (RZ) Version: 1.0
Firefox v 140 onwards.

Hold the right mouse button: roll the wheel to zoom, press the wheel button to cycle presets.

| Gesture | Effect |
| ---------------------------------------------------- | --------------------------------------------- |
| Hold right button + wheel up | Zoom in (+10% per notch |
| Hold right button + wheel down | Zoom out (−10% per notch) |
| Hold right button + press the wheel button | Cycle the presets: preset 1 → 2 → 3 (100%) |

• Zoom is clamped to the browser's limits (Firefox: (30% – 500%), Chrome based: (25% – 500%).
• Ctrl/Alt/0/-/+ + wheel is left untouched (Browser's own zoom).
• After a zoom/reset gesture, the context menu on release is suppressed so it doesn't interrupt normal operation; a plain right-click still shows the menu.

Add-on Preferences (about:addons → Right Zoom → Preferences) lets you set the first two zoom presets of the wheel-button cycle (between 30% and 500%, defaults: 150% and 125%). The third step of the cycle is always 100%.
