About this extension
Hide Sensitive Information masks sensitive fields and visible text on websites so private data is less likely to appear while you browse, present, record, or share your screen.
Features:
- Masks common sensitive fields such as passwords, email addresses, phone numbers, tokens, credit card fields, and one-time codes
- Detects sensitive inputs using field types, autocomplete attributes, labels, placeholders, and other page metadata
- Supports custom CSS selectors for site-specific or global masking rules
- Re-applies masking on dynamic pages and single-page apps as content changes
- Lets you quickly toggle masking on or off from the toolbar popup
- Stores preferences locally in browser extension storage
How it works:
- The extension processes page content locally in your browser
- It does not send webpage content to external servers
- It does not use analytics, ads, or tracking
This add-on is designed for privacy-conscious browsing, demos, screen sharing, and recordings where sensitive information should stay out of view.
