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
Getting errors?
- ERROR_ZERO_BALANCE — add funds at Dashboard
- ERROR_NO_SLOT_AVAILABLE — servers busy, retry in a few seconds
- ERROR_CAPTCHA_UNSOLVABLE — captcha couldn't be solved (not charged)
- TIMEOUT — solver took too long, try again
