Stop Autofill

Stop Autofill — take control of browser autofill Modern browsers are aggressive about autofill, password prompts, and form suggestions — and they often appear where you don’t want them. Stop Autofill gives you precise, opt-in control over where browser autofill and password managers are allowed to appear — without breaking websites or collecting data. You decide: on which websites autofill is disabled on which pages it applies or even which specific form or element should be ignored No global blocking. No tracking. No guesswork. How it works: Stop Autofill operates on an opt-in rule system: This website — disable autofill across an entire site This page — apply rules only to a specific page Block element — target a single form, input group, or container Rules are easy to create, review, export, and remove. Common use cases 🧑‍💻 Developers & IT professionals Stop password prompts on internal admin portals Prevent autofill from interfering with test forms Eliminate accidental credential injection during demos 🧾 Finance & enterprise tools Disable autofill on accounting, ERP, or ticketing systems Prevent browsers from offering unrelated saved data Reduce mistakes caused by incorrect autofill suggestions 🛒 Online shopping & checkout flows Block autofill on multi-step checkout pages Avoid incorrect address or payment suggestions Keep forms clean when entering data manually 🧪 QA, staging & testing environments Prevent autofill from polluting test data Keep test inputs predictable and controlled Avoid cached values during repeated test runs 👤 Privacy-conscious users Reduce browser-level data exposure Stop password manager prompts where they aren’t needed Maintain control without disabling autofill everywhere Element picker (surgical control) Need to block autofill on just one form? Use Block Element: Click “Block Element” from the popup or right-click menu Select a form, container, or input area Confirm the selection Perfect for sites where only part of a page misbehaves. Privacy-first by design: Stop Autofill is built to run locally in your browser. ❌ No analytics ❌ No tracking ❌ No ads ❌ No external servers What is stored on your browser: Your rules (sites, pages, selectors) Your preferences and counters All data is stored locally using browser extension storage. If browser sync is enabled, your settings may sync across devices via your browser account — Stop Autofill does not operate any servers. Customizable defaults Control how new rules behave: Disable autofill by default Disable password manager prompts Disable the right-click context menu if desired You’re always in control. Backup & portability: Export all rules to a JSON file Import rules on another browser or machine Clear all rules anytime from Settings Why Stop Autofill? ✔ Precise control instead of global blocking ✔ Works per site, per page, or per element ✔ No data collection ✔ No subscriptions ✔ No permissions beyond what’s required Open & transparent Stop Autofill is open source and maintained transparently.
