Automated captcha solving
Here you can select the types of captchas that the extension will recognize automatically.
You may need to reload the page with captcha for the changes to take effect!
Repeat captcha solving in case of an error
If the first attempt to solve the captcha is failed, the extension will send repeated tasks until the captcha is not solved, or until the limit specified in this setting will not be reached.
Proxy
Here you can specify the proxy that will be sent along with the recognition task.
The "Login" and "Password" are optional.
Blacklist control
Using the blacklist you can configure the extension to ignore captchas on specific websites.
After enabling this option, a field for entering sites will appear:
Domains must be specified along with the protocol (https:// or http://). You can use masks:
- ? - any one character except period
- * - any number of any characters
