## Description

Zoom for Firefox is a powerful browser extension designed to improve your web viewing experience by allowing custom zoom levels from 1% to 400%. Featuring a responsive slider, zoom buttons, and mouse scroll zoom, it offers precise control over webpage scaling. The extension saves zoom settings per website, ensuring your preferred zoom levels are restored automatically.

Ideal for users with vision impairments or those seeking comfortable reading, Zoom offers various zoom engines including default browser zoom, CSS zoom for smooth scaling, and font-size adjustment that targets text only.
