Default Zoom is a lightweight Firefox add-on designed to set a default zoom level for web pages, particularly beneficial for users with QHD or HiDPI monitors. This tool allows you to specify your preferred zoom level, defaulting to 100% if none is set. It respects per-site zoom settings, enhancing your web browsing experience without unnecessary complexity. With only 30 lines of JavaScript, it prioritizes minimalism and efficiency over extensive features found in other zoom extensions.

The add-on operates with a single local option for the default zoom level and requires no additional permissions, making it user-friendly and straightforward. While it does have a limitation regarding 100% zoom, which is overridden upon reloading a page, it efficiently addresses the needs of users who find standard zoom levels insufficient. Ideal for those seeking a simple yet effective solution for customizing their browsing experience.
