# Privacy-first AI Firefox Add-on: highlight text and press your shortcut with zero tracking.

Use Vezz me natively on Mozilla Firefox. Highlight text on any webpage, press your custom shortcut (default: Ctrl+Shift+X), and get instant AI answers with zero background tracking.

> **Best fit:** Best for Mozilla Firefox users (and Zen/Waterfox/LibreWolf users) who want an on-screen AI assistant without granting 'Access your data for all websites'.

## Live Webpage Walkthrough

- **Source:** Mozilla Firefox Add-ons (AMO) — Permission Prompt Comparison (`addons.mozilla.org/en-US/firefox/addon/vezz-me`)
- **Recommended Context Mode:** Minimal

**Highlighted Passage:**
> Permissions requested by Vezz me: activeTab, storage. Warning banner shown by Firefox on install: None (does not require 'Access your data for all websites').

**User Question (Shortcut):** "Why does Vezz me not trigger the 'Access your data for all websites' warning in Firefox?"

**Vezz me On-Screen Answer:**
In Mozilla Firefox, the scary **'Access your data for all websites'** prompt is triggered whenever an add-on declares `<all_urls>`, `*://*/*`, or persistent `content_scripts` in its `manifest.json`.

Because Vezz me declares only **`activeTab`** and **`storage`** (with zero host permissions and zero background content scripts), Firefox's WebExtension sandbox guarantees that Vezz me is completely blind to your browsing until you explicitly press your shortcut (`Ctrl+Shift+X` by default).

**Suggested Follow-Ups:**
- "How do I customize the shortcut in Firefox `about:addons`?"
- "Does Vezz me work inside Firefox Multi-Account Containers?"

## Step-by-step workflow

1. **Install Vezz me from Mozilla Add-ons (AMO)**: Visit `addons.mozilla.org/en-US/firefox/addon/vezz-me/` and click 'Add to Firefox'. Notice there is no 'Access your data for all websites' warning.
2. **Highlight text inside any Firefox tab or Container**: Select any paragraph on arXiv, GitHub, MDN, or Wikipedia and press your shortcut (default: Ctrl+Shift+X / Cmd+Shift+X on macOS, customizable).
3. **Import custom prompt presets via JSON**: Download any `.json` preset from our Prompt Library and import it into the Firefox extension popup.

## Zero conflicts with uBlock Origin and Multi-Account Containers

Firefox users choose Gecko for privacy, uBlock Origin, Multi-Account Containers, and Strict Enhanced Tracking Protection (ETP).

- No 'Access your data for all websites' permission required—uses strict `activeTab` + `storage`
- Zero conflicts with **uBlock Origin**, **Privacy Badger**, or **Strict ETP** because Vezz me never injects third-party iframes or tracking pixels into webpages
- Respects **Firefox Multi-Account Containers**—no background content scripts bridging state across Personal, Work, and Banking containers
