“Privacy Bubble” — Per-Tab Privacy Profiles

[Marsh1]

A Firefox feature (or add-on) that lets users assign privacy levels per tab or per container — think of it like a privacy slider that follows each tab.

🧠 How It Works

When you open a new tab, you can pick a Privacy Mode Badge:

Level Name Features Enabled Ideal Use

🟢 Normal

Balanced

Standard cookies, normal history

Everyday browsing

🟡 Guarded

Enhanced Privacy

Blocks third-party cookies, disables trackers

Reading news or light research

🔴 Stealth

Ultra Private

No cookies, no history, auto-closes on idle

Private searches, sensitive tasks Each tab shows a small “bubble icon” (🟢🟡🔴) on the tab bar — click it to toggle modes instantly. Technical Approach Uses Firefox Containers API or WebExtension storage to isolate cookies & local storage per privacy level. Dynamic headers (like DNT, Referer) adjusted based on privacy mode. Optionally integrates with Startpage, DuckDuckGo, or Brave Search in Stealth mode. Auto-closes Stealth tabs after N minutes of inactivity (user-configurable) Why It’s Unique Firefox already has Private Mode and Containers, but not an adaptive privacy layer per tab. It merges convenience + transparency + control in one intuitive visual model. Perfect for privacy-conscious users who don’t want to open full new windows constantly. Possible Implementation (for add-on devs) Using: // Example: Switch privacy level dynamically browser.webRequest.onBeforeSendHeaders.addListener( (details) => { const level = getPrivacyLevel(details.tabId); if (level === "stealth") { details.requestHeaders.push({ name: "DNT", value: "1" }); details.requestHeaders.push({ name: "Referer", value: "" }); } return { requestHeaders: details.requestHeaders }; }, { urls: ["<all_urls>"] }, ["blocking", "requestHeaders"] );
