Add-on summary

Analyze keywords

Buster is a Firefox extension which helps you to solve difficult CAPTCHAs by completing reCAPTCHA audio challenges using speech recognition. Challenges are solved by clicking on the extension button at the bottom of the reCAPTCHA widget.

It is not guaranteed that challenges are always solved, the limitations of the technology need to be considered.

The continued development of Buster is made possible thanks to the support of awesome backers. If you'd like to join them, please consider contributing with Patreon, PayPal or Bitcoin.

Client app

The success rate of the extension can be improved by simulating user interactions with the help of a client app. Follow the instructions from the extension's options to download and install the client app on Windows, Linux and macOS.

Solving more than a couple of reCAPTCHA challenges a day may lead to a temporary block, regardless of your use of the extension. Visit the wiki for more details.

Anti-fingerprinting prevents the client app from moving the mouse as expected. If privacy.resistFingerprinting has been turned on from about:config, make sure to also enable keyboard navigation from the extension's options.

This is far and above the best, and most essential broswer addon. It works great almost all the time, and when it doesn't refreshing for a new captcha prompt fixes it. Particularly now that captchas have started to become incoherent gibberish that asks you to select something nonesensical, being able to bypass them is amazing
