How JustZix works

Step 1 — Install in developer mode

JustZix is not yet published on Chrome Web Store, but you can download the current version and install it manually in 2 minutes. Developer mode in Chrome lets you load any extension from a folder on disk — it is a standard mechanism used by developers. The extension persists across browser restarts.

1. Download the ZIP from the download page.
2. Unzip — you will get a justzix/ folder.
3. Open chrome://extensions/ in Chrome.
4. Enable "Developer mode" using the toggle in the top right corner.
5. Click "Load unpacked" and select the justzix/ folder.

Step 2 — Your first rule

Open a page where you want to change something. Click the JustZix icon. Select "New rule", set a URL pattern (auto-filled from the current page) and write CSS or JavaScript code.

Example — hide all cookie banners:

[id*="cookie"], [class*="cookie-banner"], [class*="cookie-consent"] {
  display: none !important;
}

Step 3 — First JavaScript rule

Beyond CSS, you can run custom JavaScript on matching pages. Open the rule view and click the JavaScript tab. The code runs once per page load, in the page's context (access to window, DOM, fetch, etc.).

Example — auto-click "Accept" on cookie banners:

let attempts = 0;
const id = setInterval(() => {
  if (++attempts > 20) return clearInterval(id);
  const btn = [...document.querySelectorAll('button, a')]
    .find(b => /accept all|akceptuj/i.test(b.textContent));
  if (btn) { btn.click(); clearInterval(id); }
}, 500);

Step 4 — Action button (toolbar)

Switch on "Action panel" on the folder, then in the rule's Actions tab add a button. Each button has a 4-character label, color, and runs custom JS on click — perfect for repeated tasks like "fill test data" or "clear form".

Example action — clear all form fields:

// Action 'CLR' (red, 1 click clears the form)
document.querySelectorAll('input, textarea, select')
  .forEach(el => {
    if (el.type === 'hidden') return;
    if (el.type === 'checkbox' || el.type === 'radio')
      el.checked = false;
    else el.value = '';
    el.dispatchEvent(
      new Event('change', { bubbles: true })
    );
  });

Step 5 — Sync across devices

In extension settings click "Enable sync". The extension generates a 25-character key in SYNC-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX format. Save it somewhere safe (a password manager). On a second device enter the same key — all rules sync automatically.

Step 6 — Share via link

Every folder, group and rule has a "📤 Share via URL" button. You pick a TTL (1h / 6h / 12h / 24h / 48h) and get a short link justzix.com/s/JZS-XXXX-XXXX-XXXX-XXXX. Send it to the recipient — they click, see the preview, import with one click.
