## Review summary

Users appreciate 'isear' as an excellent SearchWP replacement with powerful features such as regex search and scrollbar highlights. It has evolved with a clean interface and robust automatic search detection. However, multiple users report missing hit count display, compatibility issues on certain sites, and limited autopagerize support. Requests include English translations, improved shortcut support, and more intuitive search input methods. Despite some bugs and interface quirks, it is highly valued for enhancing in-page search functionality beyond the default Firefox find.

### Pros

- Acts as a strong replacement for SearchWP, offering similar or enhanced functionality.
- Supports regular expression searches, which users find very useful.
- Highlights search results on the scrollbar, aiding navigation within the page.
- Has a simple and clean interface that improves with updates, making it user-friendly.
- Automatically detects search words from the URL bar and offers multiple search inputs, enhancing usability.

### Cons

- Lacks some features of Firefox's native find (Ctrl+F), like displaying the hit count of search results.
- Issues with compatibility on some specific websites, causing DOM elements to not generate properly unless blacklisted.
- Autopagerize integration is problematic—auto-highlight on newly loaded pages doesn't work, and some keyboard shortcuts like Ctrl+R malfunction.
- No option to toggle case-insensitive regular expression searches, limiting search flexibility.
- The search input interface isn't intuitive to all users; some desire the ability to directly type in the browser's search bar for convenience. Also, occasional bugs like incorrect search word replacement and residual highlights occur.
