Here are the key checkpoints to evaluate before adding any extension to your browser.</p> <h2 id="1-review-the-required-permissions">1. Review the Required Permissions </h2><p>When you install an extension, both Chrome Web Store and Firefox Add-ons display a list of requested permissions. This is your first line of defense.</p> <table> <thead> <tr> <th>Permission</th> <th>Risk Level</th> <th>What It Does</th> </tr> </thead> <tbody> <tr> <td><code>tabs</code></td> <td>Low-Moderate</td> <td>Read URLs of open tabs</td> </tr> <tr> <td><code>storage</code></td> <td>Low</td> <td>Save local data (common)</td> </tr> <tr> <td><code>activeTab</code></td> <td>Low</td> <td>Access only the current tab</td> </tr> <tr> <td><code>&lt;all_urls&gt;</code></td> <td><strong>High</strong></td> <td>Read data from every website you visit</td> </tr> <tr> <td><code>clipboardRead</code></td> <td><strong>High</strong></td> <td>Snoop on clipboard contents</td> </tr> <tr> <td><code>history</code></td> <td>Moderate-High</td> <td>Collect browsing history</td> </tr> </tbody> </table> <p>If a simple screenshot extension asks for <code>history</code> or <code>&lt;all_urls&gt;</code>, that&rsquo;s a major red flag.</p>
