Development

This extension has no package manager or dependency install step. Edit the plain JavaScript, HTML, CSS, and manifest files directly.

Run the syntax checks before submitting changes:

node --check background.js
node --check popup/popup.js

Manual Testing

1. Open opera://extensions.
2. Enable developer mode.
3. Load this folder as an unpacked extension.
4. Open the popup and verify cache clearing, timer save, timer disable, and status display.

Security Expectations

• Do not add host permissions unless required by a documented feature.
• Do not add cookie, history, downloads, or tabs permissions without explicit review.
• Do not add external network calls.
