Buster works by sending the audio Captcha to Google’s Web Speech API. On a slow Android connection, this API times out.

The Code-Level Fix (For Tech Users): If you are a developer or advanced user, you can adjust Buster’s timeout settings:

Iceraven is a Firefox fork. It works identically to Firefox but allows more extensions without hidden menu tricks.

If you have tried Kiwi, Firefox Nightly, and Iceraven and Buster still fails, the problem is likely Google reCAPTCHA v3 (invisible), which Buster cannot solve.

The final fix: Switch to Privacy Pass. While not Buster, Privacy Pass is an Android-friendly protocol that reduces Captchas by using cryptographic tokens. Install the Privacy Pass browser extension (available on Kiwi/Firefox). It won't solve Captchas, but it will prevent them from appearing as often.

If the audio Captcha downloads but no sound plays, Android’s media focus might be hijacked.

✅ Step 1: Install Kiwi Browser.
✅ Step 2: Add Buster from Chrome Web Store.
✅ Step 3: Go to a site with a captcha (e.g., Google’s reCAPTCHA demo).
✅ Step 4: Click the captcha checkbox.
✅ Step 5: Click the audio button (speaker icon).
✅ Step 6: Click the Buster puzzle icon.
✅ Step 7: Wait 1–2 seconds. Solved.

If step 6 does nothing:
→ Tap the microphone permission popup.
→ Restart Kiwi.
→ Try in incognito mode.

Even after installation, the Buster captcha solver for Android might glitch. Here are specific fixes for the most common runtime errors:

The Problem: Buster is a browser extension. The standard Chrome browser on Android does not support extensions. The Fix: You must use a browser that supports extensions. The best and most reliable option is Firefox for Android.
