Captcha Solver Extension for Chrome and Firefox: How to Install and Set Up

Captchas are everywhere: sign-up forms, login pages, submissions, multi-site workflows. If you deal with dozens of websites every day, solving them manually eats up a serious amount of time. A captcha solver extension fixes this: the plugin automatically detects captchas on a page, sends them to an AI server, and performs all the required actions for you. It clicks images, drags sliders, and solves puzzles.

In this article we will cover how captcha solver extensions work, which captcha types they support, and walk through a step-by-step setup of the Cap.Guru plugin for Chrome and Firefox.

How a Captcha Solver Extension Works

The concept is straightforward. The plugin integrates into your browser and monitors the pages you visit. When a captcha appears, the extension automatically identifies it, captures a screenshot or reads its parameters, and sends the data to a server where a neural network analyzes the challenge. Within a few seconds the server returns click coordinates or interaction instructions, and the plugin carries out the necessary actions right on the page.

You don't need to copy anything, paste anything, or write any code. Everything happens in the background. You simply open a website, and the captcha gets solved on its own. The whole process takes just a few seconds.

Captcha Types Supported by the Extension

The Cap.Guru plugin uses image-click and slider-drag methods. It solves captchas all the way through to the green checkmark. Here is what it supports:

reCAPTCHA v2. The most common type. The "I'm not a robot" checkbox, image grids with buses, traffic lights, and crosswalks. The plugin clicks the correct images automatically.

FunCaptcha (Arkose Labs). A captcha that asks you to rotate objects or pick the correct orientation. Common on major platforms. The plugin recognizes the position and clicks the right spots.

TikTok. The platform's own captcha that frequently appears during bulk actions. Supported since the earliest versions of the plugin.

Image captchas. Graphic captchas where you need to click specific objects or select coordinates on an image. Automated solving was added in version 1.0.5.

Other types. The plugin also handles a number of less common captchas. The list grows with every update.

Installing the Cap.Guru Captcha Solver Extension

The plugin is available for two major browsers. The current version at the time of writing is 1.0.7.

Chrome

The easiest way is to install directly from the Chrome Web Store. Go to the extension page and click "Add to Chrome." The plugin icon will appear in your extensions bar within seconds.

If you need a manual installation (for example, for anti-detect browsers): download the ZIP archive from the Cap.Guru documentation, unpack it into a folder, open chrome://extensions, enable "Developer mode," and click "Load unpacked," pointing to the plugin folder.

Firefox

For Firefox, you can install the plugin from Mozilla Add-ons. For manual installation: download the Firefox version archive, unpack it, open about:debugging, select "This Firefox," click "Load Temporary Add-on," and choose the manifest.json file from the unpacked folder.

Setting Up the Plugin

After installation, just follow three steps:

1. Open the extension by clicking the Cap.Guru icon in the browser toolbar.

2. Enter your API key. You can get one from the Cap.Guru dashboard after signing up.

3. Enable the captcha types you need. You can turn on all of them at once or just the ones you encounter most often.

After that, the plugin will start working automatically on every page where it detects a supported captcha.

Configuration via File

For advanced users, there is an option to set everything up through a config file. In the plugin's root folder, find the file called simple_config.json, rename it to config.json, and specify your API key and desired captcha types inside. This is convenient when deploying the plugin across multiple machines or automated environments.

Disabling on Specific Sites

Starting from version 1.0.7, you can disable captcha solving for individual websites. This is useful if automatic solving interferes with a particular site or triggers repeated verification checks.

Frequently Asked Questions

Does the extension slow down the browser? No. The plugin only activates when it detects a captcha on the page. The rest of the time it consumes no resources.

Does it work in anti-detect browsers? Yes. The extension is compatible with Chromium-based anti-detect browsers (Dolphin, AdsPower, GoLogin, and others). Install it by loading the unpacked extension.

What if a captcha doesn't get solved? Make sure the relevant captcha type is enabled in the extension settings and that your account is active. If the issue persists, contact Cap.Guru support.

Can I use it on multiple computers? Yes. A single API key works on any number of devices.

Do I need to update the extension manually? If you installed it from the Chrome Web Store or Firefox Add-ons, updates arrive automatically. For manual installations, you need to download the new version and replace the folder.

Conclusion

The Cap.Guru captcha solver extension handles captchas automatically: it detects them on the page, sends them to an AI server, clicks images, and drags sliders without any input from you. Installation takes about a minute, and setup comes down to entering an API key. Chrome, Firefox, and Chromium-based anti-detect browsers are all supported.

For anyone who works in a browser manually (multi-accounting, SMM, SERP analysis), this is the fastest way to get rid of captchas without writing code or dealing with complex configurations.
