VPN Frontier wot AgitAngst

What is it?
VPN Frontier is a browser extension that blocks access to Russian domain zones (.ru, .рф, .su, and others) when your IP address is outside Russia. It works at the browser level — requests are intercepted before any connection to the server. No data leaves your browser.

Why?
You're abroad and want to prevent accidental access to Russian websites. Or you want to control which domain zones are accessible from your network. VPN Frontier handles this automatically — no manual proxy or firewall setup needed.

Key Features
🔒 Block-First Architecture
On install, all Russian zones are blocked instantly — before the first IP check. Blocking is lifted only after confirming a real Russian IP address. Zero vulnerability windows.

🌍 10 Selectable IP Check Services
Choose which APIs you trust:

ipapi.co, ipinfo.io, ifconfig.co, ipwho.is, freeipapi.com
ip-api.com, ipdata.co, ipbase.com, ipgeolocation.io, ip2location.io
Toggle each independently. At least one must be active. The extension tries them in order and stops at the first success.

⚡ 6 Configurable Check Triggers
Combine any conditions — each toggles independently:

Trigger Description
Visit to a blocked site IP check on every navigation to .ru etc.
Tab switch Check when switching active tabs
Timer Periodic check (5 / 10 / 15 / 30 / 60 min)
Browser startup Check when Chrome/Firefox starts
Wake from sleep Detects laptop waking from sleep
Return to browser When switching back from another app
🏳️ Dynamic Icon
On .ru sites the extension icon becomes 🇷🇺 Russian flag. On other sites — 🌐 globe.

🌐 Full Bilingual Interface
