🔒 Security Fixes

Critical Severity

1. Remote Code Execution Prevention

Risk: High - Could allow malicious code injection
Fix: Removed unsafe remote locale loading, now uses bundled files only
Impact: Users are protected from MITM attacks and repository compromise

2. Content Security Policy Added

Risk: High - XSS attacks possible
Fix: Added CSP: script-src 'self'; object-src 'self'
Impact: Prevents cross-site scripting attacks

3. URL Injection Prevention

Risk: Medium - Malicious sites could inject content
Fix: Added encodeURIComponent() for all favicon URLs
Impact: Prevents injection via crafted hostnames

Medium Severity

4. WebSQL Security Issue

Risk: Low - Creates unnecessary databases
Fix: Only checks API presence, doesn't create test database
Impact: Cleaner, more secure WebSQL detection

5. Frame Injection Optimization

Risk: Low - Increased attack surface
Fix: Changed all_frames: true to false
Impact: Reduced attack surface, better performance
