- Version 1.2 -
New Feature: Added advanced domain filtering options
New Feature: Customizable notification timeout settings
Improved Performance: Optimized background processes for better browser performance
Enhanced UI: Redesigned settings panel for better usability
Bug Fixes: Resolved issues with certain domain configurations
- Version 1.3 -
Bug Fixes: Fixed unwanted notifications showing up for domains where CORS is not active
Improved Compatibility: Fixed issues with YouTube and Google services breaking when extension is active
Smart Domain Detection: Added intelligent detection of sites with existing CORS handling
Enhanced Notification System: Better control over when notifications appear Protected Domain
Handling: Special treatment for domains with sensitive CORS requirements
NG-Anti-CORS lets you maintain separate settings for each site, allowing you to permanently enable CORS blocking on development domains while keeping it disabled on sensitive websites - even after restarting your browser.
