Quick Answer

If you opened a Perplexity page BEFORE installing or updating the extension, you need to refresh that page for the extension to work.

Why Does This Happen?

Browser extensions work by injecting special code (called "content scripts") into web pages. However, this injection only happens when:

1. A new page is loaded (you navigate to a new URL)
2. An existing page is refreshed (you press F5 or click the refresh button)

The Problem

If you:

1. ✅ Opened Perplexity.ai in a tab
2. ✅ Then installed or updated the extension
3. ❌ The extension cannot connect to that already-open tab

This is because the extension's code was not injected into the page when it loaded.

The Solution

Simply refresh the Perplexity page (press F5 or click the refresh button), and the extension will be able to connect.

Common Scenarios

Scenario 1: Just Installed the Extension

• What happened: You installed the extension while Perplexity was already open
• Solution: Refresh all open Perplexity tabs

Scenario 2: Extension Was Updated
