Pesticide Chrome Extension

Pesticide is a lightweight Chrome extension that injects Pesticide CSS into the current webpage to outline each HTML element with distinct borders.

The extension is simple to use and doesn’t require any special permissions, ensuring a safe browsing experience. Just enable it to see clear outlines around elements and disable it when done. Users are encouraged to leave a review if they find the tool helpful, though it’s entirely optional.
