Zoom for Firefox

Zoom in or out on web content using the zoom button and mouse scroll wheel for more comfortable reading. That to each percent value. It helps you to zoom easily in and out a web page. Thanks to the slider and the zoom buttons.

Zoom for Firefox is a powerful browser extension designed to enhance your web reading and video experience by allowing precise control over page zoom levels. With its intuitive slider and zoom buttons, users can zoom from 1% up to 400%, making it ideal for those with vision challenges such as amblyopia or lazy eye. The live zoom adjusts in real-time when you scroll while holding the zoom button, offering a smooth interface.

This extension provides features like saving zoom settings per website, choosing among different zoom engines (default browser, CSS style zoom, or font size only), and managing zoom levels for all open tabs simultaneously. Additional options include displaying zoom percentages on the toolbar button, custom context menus, and magnifying glass effects around the cursor. It also supports improved video zoom on platforms like YouTube™, seamlessly integrating with the Turn Off the Lights extension for enhanced viewing focus.

Zoom for Firefox requires permissions for context menus, tab management, storage, and content access to deliver a seamless and customizable zooming experience compatible with most websites. It brings a more refined and accessible zoom functionality beyond default browser shortcuts, tailored for comfortable reading and efficient browsing.

User reviews

Users appreciate the extension's simplicity and per-domain zoom memory, making browsing comfortable especially on large screens. However, multiple reviews report issues with the magnifying glass feature not working, zoom centering problems, and platform compatibility problems. The add-on's interface and integration with Firefox's native zoom are sometimes problematic. Overall, it is functional for domain-specific zooming but has notable usability and feature shortcomings.
Pros
  • Simple and user-friendly interface with basic zoom controls (+, -, 100%)
  • Remembers zoom levels per domain, so when returning to a site, the chosen zoom level is retained
  • Allows setting zoom levels individually for each domain
  • Works well for large screens where default text size is too small
  • Support is responsive and helpful
Cons
  • Magnifying glass feature does not work or is broken in the current version
  • Zoom is not always centered and tends to zoom into the left part of websites
  • Does not work properly on all platforms (e.g., Android Firefox, Mac OS)
  • Context menu and options page are poorly designed and hard to access
  • Does not integrate well with Firefox's native zoom functionality
