Debloat por 301.st

Tired of AI features you never asked for? Copilot popping up in Edge, AI Overview cluttering Google Search, Gemini suggestions appearing out of nowhere, shopping pop-ups on every product page?

Debloat gives you back control. One extension, three browsers, zero bloat.

What Debloat Removes

AI FEATURES
Hide Google AI Overview and AI Mode from search results. Block Copilot sidebar, "Help Me Write", Visual Search overlay, and text predictions in Edge. Disable Gemini suggestions and AI tab organization in Chrome. Remove AI chatbot sidebar, link previews, and tab group suggestions in Firefox. Prevent websites from accessing experimental Web AI APIs (window.ai).

SPONSORED CONTENT
Remove MSN news feed, sponsored tiles, and "Spotlight" recommendations from Edge new tab page. Hide Google Discover cards in Chrome. Block sponsored stories, recommended articles, and promoted top sites on Firefox Home.

SHOPPING TOOLS (Edge)
Disable Shopping Assistant, price comparison pop-ups, coupon notifications, and express checkout suggestions that appear on retail websites.

TELEMETRY & TRACKING
Block diagnostic data, usage reports, and crash reporting endpoints for Chrome, Edge, and Firefox. Disable Firefox Studies (Shield experiments) that silently modify browser behavior.

ANNOYANCES
Remove Microsoft Rewards prompts, "Set as default browser" nags, feature recommendation banners, DALL-E theme suggestions, "Edit with Acrobat" buttons, Bing redirect on Edge new tab search, and auto sign-in prompts.

How It Works

Debloat uses three layers of protection:

1. Network-level blocking — Intercepts requests to AI, telemetry, shopping, and ad endpoints before they reach the server. Uses the browser's built-in declarativeNetRequest API for maximum performance.
2. CSS injection — Hides unwanted UI elements (AI Overview cards, Copilot buttons, sponsored tiles) instantly at page load, before you see them flash on screen.
3. DOM monitoring — Catches dynamically injected elements that appear after page load, like pop-ups and floating widgets.
