AZcaptcha Browser Extension

The AZcaptcha extension automatically detects and solves CAPTCHAs on any webpage using the azcaptcha.com solving service.

Supported Captcha Types:

reCAPTCHA v2 — checkbox and invisible variants
reCAPTCHA v3 — score-based verification
hCaptcha — image selection challenges
Cloudflare Turnstile — Cloudflare's smart captcha
FunCaptcha (Arkose Labs) — interactive puzzles
GeeTest v3/v4 — slide and click captchas
Image Captcha — text recognition from images

API Key

To use the extension, you need an AZcaptcha API key:

Create an account at azcaptcha.com/register
Add funds or subscribe to a plan at Pricing
Copy your API key from Dashboard → API Keys
Click the extension icon → paste your API key → click Login

You can use either a Pay-Per-Use key (charged per solve) or a Subscription key (daily limit from your plan).

Enable Plugin

The main toggle enables or disables the extension globally. When disabled, no captchas will be detected or solved.

You can also enable/disable specific captcha types individually in the popup settings.

Supported Captcha Types

Each captcha type can be toggled on/off independently:

Enabled	Extension will detect this captcha type and show a "Solve" button
Auto Solve	Extension will automatically start solving without clicking the button

Auto Solve

When "Auto Solve" is enabled for a captcha type, the extension will automatically begin solving as soon as the captcha is detected on the page — no manual click needed.

Recommended for automated workflows. Not recommended for casual browsing (uses API credits).

Auto Submit Forms

When enabled, the extension will automatically submit the form after the captcha is solved.

Delay: Set a delay (in seconds) between solving and submitting to allow page scripts to process the token.

You can also define custom AutoSubmit rules for specific URLs in the Settings page.

Proxy Settings

Configure a proxy for captcha solving. The proxy is sent to AZcaptcha servers and used by our workers when solving the captcha.

Supported types: HTTP, SOCKS4, SOCKS5

Format: ip:port or login:password@ip:port

We recommend ProxyAZ residential proxies for best results.

Image Captcha Solving

For image-based text captchas (type the letters you see):

Right-click the captcha image
Select "Mark as captcha source" from the context menu
Click on the input field where the answer should go
The extension will remember this and solve it automatically next time

Troubleshooting

Extension not solving captchas?

Check your API key is correct (popup should show your balance)
Check the captcha type is enabled in settings
Check your balance is sufficient
Check the URL is not in the blacklist
Try reloading the page

ERROR_ZERO_BALANCE — add funds at Dashboard
