## Review summary

Users generally rate LibrusPro as a highly useful and reliable Firefox add-on. Repeated praise includes strong recommendations and the sense that it makes Librus access easier and more practical. Reviewers note that it works well over long-term use (over a year) and adds value to daily Librus workflows. One user reported a permission-related issue that prevents functionality for their setup, but this seems isolated. A minor nod to a fun easter egg (login history) and, in at least one review, the addition of a dark mode feature. Overall, the add-on is well-regarded and favored by users.

### Pros

- Highly recommended and consistently praised by users
- Very useful plugin that users find practical
- Reliable and effective, with reports of long-term use (over a year)
