Browser extensions
Real, verified CAPTCHA solver extensions for Chrome, Firefox, and Edge — with supported CAPTCHA types, solving method, account requirements, and honest best-use notes so you can pick the right one.
Overview
A CAPTCHA solver browser extension watches the page for a challenge, captures its parameters (the sitekey and URL, or an image), and sends them to a solving backend. The backend — AI, human workers, or a hybrid — returns a token or answer, which the extension injects so the form can be submitted. Most provider extensions are tied to an account and draw from a balance; a few have a free tier, and Buster is open source.
The right extension depends on the CAPTCHA types you face, whether you prefer AI or human-assisted solving, the browsers you use, and your budget. The cards below list verified options with those details side by side.
When they help

A browser add-on that detects a CAPTCHA on the page, sends it to a solving backend (AI or human-assisted), and injects the returned token or answer so you can continue — without writing any code.
A few offer a free tier or are open source (for example Buster, for reCAPTCHA audio). Most provider extensions draw from a funded account and are billed per solve.
Most support Chrome and other Chromium browsers (Edge, Opera, Brave); several also publish a Firefox add-on. The supported browsers are listed on each card.
Provider extensions usually require an account or API key tied to your balance. Open-source options like Buster do not. Each card notes whether an account is required.
