Review summary

Violentmonkey is widely praised as an open-source, privacy-conscious, and Firefox-optimized userscript manager that is easy to use and lightweight. Users appreciate its script management and customization capabilities. However, the most consistently mentioned drawback is sync reliability, including instances of script data being deleted or corrupted during syncing. Overall, it offers strong value for Firefox users who want control over their scripts, but users should back up data due to sync risks.
Pros
  • Open-source with a clear privacy stance
  • Easy to install, manage and run user scripts
  • Lightweight and fast – no bloat or slowdowns
  • Strong Firefox optimization and overall browser performance
  • Good for personalizing and enhancing websites through scripts
Cons
  • Sync reliability issues: script data can be lost or corrupted during synchronization
