Cloudflare solving in the CapSkip Custom Browser, and Fast Solve for reCAPTCHA v2

AddedImprovedFixed
Added
  • Cloudflare solving in the CapSkip Custom Browser, now the default for Cloudflare challenges: 29% faster average solve time and 13% less CPU per solve, with the success rate unchanged at 100%
  • Fast Solve for reCAPTCHA v2, solving in under 10 seconds with residential or mobile proxies. It is on by default in reCAPTCHA advanced settings, and if it fails the task switches to grid solving automatically.

Improved
  • Simplified reCAPTCHA advanced settings by removing options that are no longer needed now that the Custom Browser is stable for reCAPTCHA
Fixed
  • Proxy changes not taking effect until restart. After switching reCAPTCHA, Cloudflare Turnstile, GeeTest, CaptchaFox or Friendly Captcha to No Proxy, new tasks kept using the old proxies even though the task list showed them as Direct
  • HTTPS proxies not working on the Custom Browser path for Cloudflare and reCAPTCHA
  • Incorrect balance responses from the 2Captcha-compatible API
