Tired of solving CloudFlare captchas for half the websites you visit because you're using a VPN or TOR? This add-on is for you.

CloudFlare is a great service, and there's nothing wrong with having to solve captchas to prove you're not a robot, but it can get very tedious since their clearance cookie is not applied to other websites, prompting you to solve a captcha for each and every website you visit that is using their service.

This add-on stores the user agent and clearance cookie when you solve a captcha, and re-uses it on other websites as long as it's still valid, easing the pain during your browsing session.

It can also sync your clearance cookies using the CloudHole API, allowing you to re-use them on other devices, embedded systems or API calls which can't use a full browser to solve those captchas.

please allow usage of uuid for api key, because 7 bytes is to less entropy / easily bruteforced. possible cookie stealer? Save failed: Must provide a User Agent and Cookies.

From the moment I started using it I noticed a much improved browsing experience. Makes the use of a VPN while browsing tolerable again!
