Zen Browser Offline Guide

How to use CannaNote offline in Zen Browser, manage cached data, and install as an app.

Zen Browser Offline Guide

Zen is a privacy-focused browser built on Firefox. Since it uses the Gecko engine, most Firefox instructions apply here too.

Installing CannaNote

  1. Visit cannanote.app in Zen
  2. Look for an install icon in the address bar or menu
  3. Follow prompts to install
  4. CannaNote opens in its own window

Note: Zen's PWA support follows Firefox's implementation. If install options aren't visible, the web version works great.

Managing Cached Data

Clear Cache Only (Safe)

This removes downloaded pages but keeps your journal entries.

  1. Open Settings (usually via ☰ menu)
  2. Go to Privacy & Security
  3. Find Cookies and Site Data
  4. Click Clear Data
  5. Check "Cached Web Content" only
  6. Make sure "Cookies and Site Data" is unchecked
  7. Click Clear

View Stored Data

  1. Open Settings
  2. Go to Privacy & Security
  3. Find Cookies and Site Data
  4. Click Manage Data
  5. Search for cannanote.app

Developer Tools

Zen uses Firefox's developer tools.

Open DevTools

Press F12 or Ctrl+Shift+I (Cmd+Option+I on Mac)

View Service Worker

  1. Open DevTools (F12)
  2. Click the Application tab
  3. In the sidebar, click Service Workers

Unregister Service Worker

  1. Open DevTools (F12)
  2. Go to Application → Service Workers
  3. Click Unregister
  4. Refresh the page

Zen-Specific Notes

Privacy Features

Zen emphasizes privacy and customization. Like Firefox, its privacy features don't interfere with CannaNote:

  • We use no third-party trackers
  • All storage is first-party
  • Your data stays on your device

Customization

Zen is known for its customizable interface. CannaNote adapts to your system theme (light/dark), so it should blend with however you've configured Zen.

Updates

Since Zen is Firefox-based, it benefits from Firefox's security updates. Keep your browser updated for the best experience.

Community

Zen has an active community. If you run into browser-specific issues, their community channels may have insights. For CannaNote-specific issues, reach out to us directly.
