There’s been an add-on called Privacy Pass for a few years now. This plugin gives you 30 passes for CF and 5 passes for hCaptcha when you solve one. For example, once you solve 1 captcha for Cloudflare, you will not see 30 captchas again! It will automatically pass.
The good thing is, it’s perfectly legal. Powered by Cloudflare and hCaptcha. Valid for Chrome and Firefox.
Any bypass of hcaptcha and powered by Cloudfare would be legal. There is no legal requirement to go through those services.
However these extensions most likely enhance the tracking provided to these services, in exchange for not exploiting you as much to train their AI.
