## Review summary

Users praise Blue Blocker for strong blocking of bots/trolls and mental-health benefits, calling it essential. However, reliability is hampered by maintenance gaps, X.com compatibility issues, and recurring errors. Notable bugs include non-working skip-retweet settings and followed-account blocking, plus a cumbersome update/install process. When it’s working, it’s powerful; when not, it’s brittle and poorly maintained.

### Pros

- Strong blocking of bots/tollowers and other unwanted accounts, improving the Twitter/X experience and mental health.
- Widely regarded as an essential feature that helps users navigate Twitter/X amid paid exposure and high bot activity.
- Reliable and effective when it’s functioning, with users noting smooth performance and positive results.
- Can run as a temporary add-on and still block effectively, offering flexibility in installation.
- Users describe the add-on as incredible and the best thing to happen to Twitter, underscoring its value when working.

### Cons

- Long-term maintenance gap: many reports of no updates for months and ongoing errors, suggesting the project is abandoned or under-supported.
- Compatibility problems after Twitter’s switch to X.com, including outdated domain checks and slow/patched updates, leading to non-functionality for many users.
- Specific feature bugs like the "Skip blocking retweets from people I follow" setting not working and occasional blocking of followed accounts.
- Frequent errors, popups, and occasional account logout when blocking too quickly, reducing reliability.
- Cumbersome installation/update process (often requiring manual GitHub/temporary add-on installs) and slow or uncertain Mozilla approval.
