CAPTCHA Not Working? Try These 5 Quick Fixes

CAPTCHAs are designed to verify that you’re human, but sometimes they stop working—leaving you stuck on a verification page with no clear way forward. Whether you’re trying to log into an account, submit a form, or access a website, a broken CAPTCHA can be frustrating.

The good news is that most CAPTCHA problems have simple solutions. In most cases, you can fix the issue in just a few minutes by trying one of the methods below. We’ll walk you through the fastest fixes to try first, and when to move to the next option if needed.

Why CAPTCHAs Stop Working

Before jumping into fixes, it helps to understand why CAPTCHAs fail. Common causes include:

  • Browser cache and cookies — Old data can interfere with verification
  • Browser extensions — Ad blockers and privacy tools sometimes block CAPTCHA scripts
  • Outdated browser — Older browsers may not support modern CAPTCHA technology
  • JavaScript disabled — Most CAPTCHAs require JavaScript to function
  • Network or server issues — Temporary connectivity problems on either end

Now let’s move through the fixes, starting with the quickest ones.

Fix 1: Refresh the Page (Start Here)

This is the fastest fix to try first. Many CAPTCHA failures are temporary and resolve with a simple page refresh.

How to do it:

  1. Press F5 on your keyboard (or Ctrl + R on Windows, Cmd + R on Mac)
  2. Wait for the page to fully load
  3. Try the CAPTCHA again

If the CAPTCHA loads and works, you’re done. If not, move to the next fix.

Fix 2: Clear Your Browser Cookies and Cache

Stored cookies and cached data can sometimes interfere with CAPTCHA verification. Clearing them often solves the problem.

For Chrome:

  1. Click the three-dot menu in the top-right corner
  2. Select Settings
  3. Click Privacy and security on the left sidebar
  4. Click Clear browsing data
  5. Select All time from the time range dropdown
  6. Check Cookies and other site data and Cached images and files
  7. Click Clear data
  8. Refresh the page and try the CAPTCHA again

For Firefox:

  1. Click the hamburger menu (three horizontal lines) in the top-right corner
  2. Select Settings
  3. Click Privacy & Security on the left
  4. Scroll to Cookies and Site Data
  5. Click Clear Data
  6. Check both Cookies and Site Data and Cached Web Content
  7. Click Clear
  8. Refresh the page and try again

For Safari:

  1. Click Safari in the top menu
  2. Select Clear History
  3. Choose All history from the dropdown
  4. Click Clear History
  5. Refresh the page and try the CAPTCHA again

After clearing your cache and cookies, try the CAPTCHA once more. This fix resolves the issue in many cases.

Fix 3: Disable Browser Extensions

Browser extensions—especially ad blockers, privacy tools, and VPNs—can block CAPTCHA scripts from loading properly. Temporarily disabling them often fixes the problem.

For Chrome:

  1. Click the three-dot menu in the top-right corner
  2. Hover over More tools
  3. Click Extensions
  4. Toggle off each extension one at a time (start with ad blockers and privacy tools)
  5. After disabling each extension, refresh the page and test the CAPTCHA
  6. Once you find the problematic extension, you can leave it disabled or adjust its settings

For Firefox:

  1. Click the hamburger menu in the top-right corner
  2. Select Add-ons and extensions
  3. Click Extensions on the left
  4. Toggle off extensions one at a time
  5. Refresh the page and test the CAPTCHA after disabling each one

For Safari:

  1. Click Safari in the top menu
  2. Select Preferences
  3. Click the Extensions tab
  4. Uncheck extensions to disable them
  5. Refresh the page and test the CAPTCHA

Tip: If disabling extensions fixes the issue, you can re-enable them one at a time to identify which one was causing the problem. Then you can adjust that extension’s settings to allow CAPTCHAs on that specific website.

Fix 4: Try a Different Browser

If the CAPTCHA still isn’t working, the issue might be specific to your current browser. Trying a different browser can help you determine if it’s a browser-specific problem.

Try one of these:

  • Chrome (if you’re using Firefox or Safari)
  • Firefox (if you’re using Chrome or Safari)
  • Safari (if you’re using Chrome or Firefox)
  • Edge (Microsoft’s browser, a good alternative)

Open the website in the new browser and attempt the CAPTCHA. If it works in a different browser, the problem is likely specific to your original browser’s settings or extensions.

What to do next: Go back to your original browser and try Fix 2 (clear cache) or Fix 3 (disable extensions) more thoroughly.

Fix 5: Check Your Internet Connection and Enable JavaScript

CAPTCHAs require a stable internet connection and JavaScript to be enabled in your browser. If other fixes haven’t worked, check these settings.

Test your internet connection:

  1. Open a new tab and visit a simple website like google.com
  2. If that site loads quickly, your connection is fine
  3. If it’s slow or doesn’t load, restart your router or contact your internet provider

Enable JavaScript:

JavaScript is usually enabled by default, but if you’ve disabled it, CAPTCHAs won’t work.

For Chrome:

  1. Click the three-dot menu and select Settings
  2. Click Privacy and security
  3. Click Site Settings
  4. Click JavaScript
  5. Make sure Allowed (recommended) is selected

For Firefox:

  1. Type about:config in the address bar and press Enter
  2. Click Accept the Risk and Continue
  3. Search for javascript.enabled
  4. Make sure it’s set to true

After enabling JavaScript, refresh the page and try the CAPTCHA again.

When to Contact Support

If you’ve tried all five fixes and the CAPTCHA still isn’t working, the problem may be on the website’s end. Here’s what to do:

  • Contact the website’s support team — Use their contact form or email to report the issue
  • Provide details — Tell them which browser you’re using, what error message you see (if any), and which fixes you’ve already tried
  • Ask for an alternative verification method — Some sites offer phone verification or email confirmation as alternatives to CAPTCHAs

Conclusion

Most CAPTCHA problems can be solved quickly by trying these five fixes in order: refreshing the page, clearing cache and cookies, disabling extensions, trying a different browser, and checking your internet connection and JavaScript settings.

Start with the simplest fix (refresh) and work your way down. In the majority of cases, one of these solutions will get your CAPTCHA working again within minutes. If none of these work, the issue is likely on the website’s side, and contacting their support team is your best next step.
