3.2 Explanation of each setting

There are two parameter configurations you can tweak during the resolution of the reCAPTCHA v2

Delay between start solve captcha (ms):

This setting determines the time delay between starting the solving process for each captcha challenge.
It is measured in milliseconds (ms), and you can adjust the value based on your preference.
A higher delay can provide more time for the extension to process and solve the captcha, but it may increase the overall solving time.

Repeat captcha solving in case of an error:

This setting controls whether the extension should automatically retry solving a captcha in case of an error during the initial attempt.
The number of repeat attempts may vary depending on the specific error encountered.

3.3 Manual solving

The manual solving feature means that when the target website presents a Captcha, the extension will not automatically solve it. Users need to click the button next to the Captcha to initiate the resolution process.

3.6 How to use callback

Callback feature in the CapSolver extension, follow these steps:
