## Review summary

Users praise the add-on for actual text replacement, full-page scope, and a simple, lightweight design. But the top drawbacks are a duplication bug, limited cross-site support/maintenance, and missing advanced features like saving patterns and shortcuts. Overall, it’s a handy, quick-find-and-replace tool for simple tasks, with room for broader site compatibility and more control features.

### Pros

- Actual text replacement (not just a visual change) inside text boxes and on webpages.
- Replaces all occurrences, not just the first match.
- Simple, lightweight tool with a small footprint and easy to use.
- Works in contexts where other tools fail (including dynamic content and iframes after updates).
- Developer responsiveness and improvements (notably updates that expanded support).

### Cons

- Duplication bug in recent updates causes replacements to be applied twice.
- Limited cross-site support and maintenance; perceived as not working broadly (sometimes Google Translate only) and not updated for a long time.
- Lacks advanced features and controls (no save/favorites/history, no keyboard shortcuts, limited customization).
- If used to replace many terms at once, it can be risky due to lack of granular control.
