Whether you’re writing an email, editing a blog post, or filling out a form, these steps will get Grammarly back up and running fast.

What Causes grammarly extension not loading

• Extension disabled or inactive: If the Grammarly icon appears gray in your toolbar, the extension is turned off for that site or globally. Clicking it and enabling “Check with Grammarly” often resolves the issue immediately.
• Browser cache or cookie conflicts: Corrupted or outdated cache data can prevent the extension from initializing properly. Clearing cookies and site data frequently restores normal functionality.
• Network restrictions: Firewalls, corporate networks, VPNs, or proxy servers may block Grammarly’s connection to its servers, leading to loading failures or “Something went wrong” messages.
• Incompatible text fields: Some websites use iframes or custom input boxes that Grammarly doesn’t support, making the extension appear unresponsive even when it’s working elsewhere.

Quick Fix – Try This First (30 Seconds)

Before diving into complex troubleshooting, try this simple check—it works for 80% of users:

1. Look at your browser’s toolbar. If the Grammarly “G” icon is gray, click it.
2. Toggle on “Check with Grammarly” if it’s off.
3. Refresh the page and start typing—you should see suggestions appear.

If the icon is missing entirely, right-click your toolbar, select “Manage extensions,” and ensure Grammarly is enabled.

Complete Step-by-Step Fix Guide

1. Enable Grammarly on the current site: Click the gray Grammarly icon and turn on checking. Some sites disable it by default for privacy reasons.
2. Allow Grammarly in incognito mode (even if you’re not using it): Go to chrome://extensions, find Grammarly, click “Details,” and toggle “Allow in incognito.” This resets permissions and often fixes loading issues.
3. Clear browser cache and cookies: Go to your browser settings, clear browsing data (last 24 hours or all time), then restart the browser. This removes corrupted session data interfering with the extension.
4. Update your browser: Outdated browsers may lack APIs Grammarly needs. Update Chrome, Edge, or Firefox to the latest version from their official sites.
5. Reinstall the Grammarly extension: Remove it from your browser, then reinstall it fresh from the official Chrome Web Store or equivalent for your browser.
6. Disable conflicting extensions: Ad blockers, privacy tools, or other writing assistants can clash with Grammarly. Temporarily disable them one by one to identify the culprit.
7. Check your network: Turn off your VPN, proxy, or firewall temporarily. If Grammarly loads afterward, adjust your network settings to allow connections to grammarly.com and api.grammarly.com.

Advanced Fixes

If you’re a developer or use Grammarly in custom environments, deeper issues may arise:

• Verify Content Security Policy (CSP): If you’re embedding Grammarly in a web app, ensure your CSP allows scripts from Grammarly’s domains.
• Check API connectivity: Use browser DevTools (Network tab) to see if requests to https://api.grammarly.com are failing. Blocked requests indicate network-level filtering.
• Reset extension state via flags (Chrome only): Navigate to chrome://flags and reset all flags to default. Some experimental features can break extension behavior.

// Example: Check blocked requests in DevTools Console

fetch('https://api.grammarly.com/v1/auth')
  .then(res => console.log(res.ok ? 'Connected' : 'Failed'))
  .catch(err => console.error('Network block:', err));
