❓ FAQ

1. Do I need coding experience to use the CapSolver browser extension?

No. The extension works automatically once your API key is added — no scripts or code required.

2. Can the extension detect all reCAPTCHA types?

Yes. It supports reCAPTCHA v2, Invisible reCAPTCHA, and reCAPTCHA v3, including Enterprise variants.

3. Why do I need to keep the CapSolver panel open during detection?

The CAPTCHA parameters are captured live from the browser’s activity. Closing the panel stops the listener and prevents proper detection.

4. Does the extension work on any website?

It works on sites using standard CAPTCHA formats. It does not bypass custom anti-bot firewalls or non-CAPTCHA blocks.

5. Do I need funds in my account to solve CAPTCHAs?

Yes. The extension requires an active balance to submit and solve CAPTCHA tasks.

6. Can I use the same API key on multiple browsers or devices?

Yes, as long as it's within your account security preferences and usage limits.

7. What should I do if detection does not show any parameters?

Refresh the page, ensure the panel stays open, and trigger the CAPTCHA again. Some websites delay the widget loading until interaction.
