## Review summary

User feedback is mixed: several users find the add-on effective and fast for regex searching (including large pages and targeted tasks), while many others report it fails or misses matches on complex pages. Common complaints target usability (clunky UI, no auto-scroll/keep-open, output options) and occasional stability issues under heavy use.

### Pros

- Works well for many users — able to find regex matches in pages (including YouTube)
- Fast performance on large pages compared with other extensions
- Useful for advanced/targeted searches (supports complex regex)

### Cons

- Unreliable for many users — reports of it not working or missing visible text, and problems with frames/iframes or complex pages
- Usability shortcomings — clunky UI, no auto-scroll to results, can't keep the panel open, and limited output-format options
- Stability concerns when driven hard — can freeze the browser if overloaded
