Review Summary

Pesticide was a highly valued Chrome extension for debugging CSS with simple outlines showing element boundaries. However, a recent update added distracting background colors and broke key features like the Ctrl key annotations, frustrating many users. People also report difficulty toggling the tool off without a page reload. The prior simplicity and usefulness of the extension was praised, but the latest changes have degraded the user experience, leading to calls for reverting or fixing the update.

Pros

  • Historically very useful and invaluable for CSS troubleshooting and frontend development.
  • Simple and effective when it was just outlining elements without background colors.
  • Easy to use and highly rated prior to recent updates.
  • Used and recommended in web development education contexts.
  • Highly regarded for helping visualize divs and page structure.

Cons

  • Recent update introduced bright background colors that make it hard to see and debug CSS.
  • Ctrl key function (for showing div dimensions and annotations) stopped working after update.
  • Cannot toggle the extension off without reloading the page in the new version.
  • Users dislike the forced colorful block layout replacing the plain outlines.
  • The update removed essential functionality and usability, leading to many uninstallations.
