## Review summary

User reviews praise faster loading, reduced buffering, reliable preloading, and strong subtitle and audio controls across many sites. Recurrent drawbacks focus on YouTube compatibility, conflicts with some extensions, and inconsistent quality selection on certain sites.

### Pros

- Significantly faster loading and reduced buffering across many streaming sites, even on slower connections.
- Pre-download/preload features improve reliability and smooth playback during outages.
- Robust subtitle support with customizable options, including anime sites and foreign-language videos.
- Integrated audio controls and an equalizer provide better sound quality and lip-sync.
- Works across a wide range of sites, delivering a generally smoother playback experience.

### Cons

- YouTube compatibility issues: the extension does not work well with YouTube and can break there.
- Conflicts with other extensions (e.g., Firefox Multi-Account Containers and SponsorBlock) causing the player to fail or load behind the site.
- Quality/stream selection can be confusing or insufficient: not all quality levels are shown and auto-selection can pick too high a quality, leading to loading problems.
