Active Session Heartbeat (New!): Say goodbye to unexpected timeouts! VisaSentinel now fires a lightweight, invisible background ping every 4 to 7 minutes. This acts as a digital "keep-alive" signal, preventing both Cloudflare and Azure B2C sessions from timing out due to inactivity—even if you've set your appointment check interval to 10 minutes or more. You can now leave the extension monitoring completely hands-off.
Intelligent Cloudflare Recovery: We’ve completely rebuilt our 403 API blocking logic. Instead of just pausing checks when Cloudflare blocks a background request, the extension now actively intercepts the block and automatically reloads the page to present the visual security challenge checkbox. Once you click it, monitoring resumes seamlessly without skipping a beat.
Check Start Guard: Added robust safety limits to prevent overlapping check cycles and block rapid repeat check starts, ensuring your account stays safe from portal rate-limiting.
Retry Storm Prevention: App-driven OFC dropdown resets and location re-selections no longer accidentally trigger the page-ready recovery loop.
Daily Limit Protection: Forced and manual refreshes now properly respect your configured daily check limit and active-check safeguards.

Added

• License Device Limits: Added Payhip Software Activation endpoints to prevent unauthorized sharing of license keys. License keys are now bound to specific browsers using usage limit counters on the Payhip backend.
• Firefox Port: Officially added support for Mozilla Firefox. Built a standalone Firefox extension package adhering to all MV3 and AMO security guidelines, including the new data_collection_permissions requirements.
• Hive Mind (Crowdsourced Alerts): Integrated a high-performance crowdsourced slot detection network. Users silently scout for slots, and when a slot is detected, the server instantly broadcasts notifications to all Pro users (via Telegram alerts and synthesized in-browser chimes), even if they are not logged in or active. The extension now automatically detects which OFC Post you are monitoring and intelligently filters crowdsourced alerts so you only receive notifications for that specific location. Included server-side 15-minute debouncing per consulate to prevent alert spam.
