Chrome Permission Audit

Chrome 'tabs' permission vs activeTab: can AI extensions read your browsing history?

Understand why Chrome warns 'Read your browsing history' when an extension requests the 'tabs' permission—and how it differs from the history and activeTab permissions.

Best fit

Best for users wondering why an extension's install prompt mentions 'Read your browsing history' even when it didn't ask for the 'history' permission.

Legitimate uses vs. red flags
What to verify before granting this permission to an AI browser tool.

Legitimate AI reading uses

  • Opening a welcome/onboarding page (`chrome.tabs.create`) when the extension is first installed
  • Sending a message from the extension popup (`chrome.tabs.sendMessage`) to the active tab to preview UI settings
  • Reading the URL and title of the current tab when attaching page context to a user's question

Red flags to watch for

  • Listening to `chrome.tabs.onUpdated` on every tab change and streaming every visited URL to a remote analytics server
  • Combining `tabs` with the actual `history` permission without a clear bookmark/history search feature
How Vezz me handles this: Vezz me never logs your browsing history. Tab messaging is used locally to preview your UI customization settings and open the welcome guide on install, and page URL/title context is sent only when you trigger a question (and can be disabled in Minimal context mode).
Step-by-step workflow

How to run this workflow in place.

1

Distinguish 'tabs' from 'history'

The `tabs` permission cannot read your past Chrome history database (`chrome://history`). Chrome uses the 'Read your browsing history' warning phrase because `tabs` exposes the `.url` and `.title` properties of currently open tabs.

2

Check why the extension uses chrome.tabs

Extensions use `chrome.tabs.query` and `chrome.tabs.sendMessage` to communicate between the toolbar popup and the webpage overlay.

3

Control URL context in settings

Choose an AI reading tool that lets you control whether the page URL and title are included in your prompt context.

Key details

Why this approach works better than switching tabs.

Why Chrome shows 'Read your browsing history' for the tabs permission
This is one of the most misunderstood warnings in Chrome. Even if an extension never requests the `history` permission, requesting `tabs` triggers the same install warning string.
  • The `tabs` API exposes four sensitive fields on open tab objects: `url`, `pendingUrl`, `title`, and `favIconUrl`
  • It does NOT grant access to your historical browsing log from yesterday or last week
  • Many extensions use `chrome.tabs` simply to send a settings-preview message from the popup to the active tab
How URL and title context improve AI answers
When you highlight a sentence like 'The limit was raised to 64KB in version 3.2', the AI needs to know whether you are reading PostgreSQL docs, AWS Lambda docs, or a Linux kernel patch.
  • Attaching the page title and URL grounds the explanation in the right technology or domain
  • In Vezz me, this metadata is only attached at the moment you press your shortcut
  • Switching Vezz me to 'Minimal' context strips page metadata if you only want the raw selected text sent
Frequently asked questions

Common questions about chrome permission audit.

Can an extension with the 'tabs' permission see websites I visited before installing it?

No. Only the separate `history` permission grants access to Chrome's historical browsing database. The `tabs` permission only interacts with currently open browser tabs.

Why does Vezz me include page title and URL in Basic/Detailed context modes?

So you don't have to explain what website you are on every time you ask a question. If you highlight a method name on an API documentation page, knowing the page title tells the AI which framework or library you are reading.
