## Review summary

Users praise Font Changer for its easy interface, instant font switching, use of system fonts across sites, and persistent preferences that improve readability. However, common downsides include a very small predefined font list with no option to add custom fonts, occasional rendering issues such as icons breaking or font substitutions on some sites, and compatibility gaps across browsers and mobile platforms.

### Pros

- Personalization by using system-installed fonts on the user's machine across all sites.
- Preferences persist across sessions with a one-click option to restore original fonts.
- Notable readability improvements (eye-strain reduction) reported by several users.

### Cons

- Very limited predefined font catalog with no support for adding custom fonts (repeated across multiple reviews).
- Rendering and layout issues on some sites (e.g., icons disappearing, font substitution like Times New Roman) when changing fonts.
- Cross-browser and platform compatibility limitations (not working on some forks like IronFox; not available on mobile apps).
