App-Nag Blocker by Lane

Tired of websites constantly nagging you to install their app? App-Nag Blocker automatically detects and dismisses those annoying "Open in App", "Get the App", and "Continue in Browser" prompts so you can browse in peace.

Features:

• Automatically detects app-nag modals and banners using text pattern matching
• Finds and clicks dismiss buttons to cleanly close prompts
• Per-site whitelisting if you want to see prompts on specific sites
• Global on/off toggle
• Minimal performance impact - detection stops after 10 seconds per page
• No data collection - fully private

Works on:

• Instagram
• LinkedIn
• X/Twitter
• And many other sites using common app-nag patterns

How it works:

The extension scans for fixed-position elements containing phrases like "open in app", "get the app", or "better in the app". When detected, it finds and clicks the dismiss button (like "Not now" or "Continue in browser") to close the prompt cleanly.

Click the toolbar icon to toggle the extension or whitelist specific sites.
