Privacy & Telemetry (Optional, Opt-in Only)

This update introduces a strictly optional analytics module designed for minimal, privacy-first usage insights.
What’s collected (only if you opt-in):
Anonymous daily capture count
Output format preference (SiFR v1 / v2)
Capture type ratio (element vs. full-page)
Random UUID per installation (for aggregate DAU/MAU only)

What’s never collected:
Page content
URLs or browsing history
Personal data
External identifiers
Any DOM data itself

Data is sent once per day using a scheduled alarm. All telemetry can be declined on first run and disabled anytime.
Privacy policy: https://insitu.im/e2llm/privacy

SiFR v2 Output Format

The new SiFR v2 format provides a richer and more structured DOM snapshot for LLMs.

Key improvements:
New 5-block structure: METADATA → NODES → SUMMARY → RELATIONS → DETAILS
Salience-based scoring (high/med/low) for smarter token budgets
Spatial clustering with automatic role detection (header, footer, nav, card, etc.)
Relation extraction (alignment, proximity, containment)
Action markers (clickable, fillable, hoverable)
Full-page capture mode with relaxed limits
Smart token budgeting based on salience + structure
CSS shorthand optimization for cleaner output

⚙️ Technical Changes

Added alarms permission to support scheduled telemetry (opt-in only)
Added BSL 1.1 license header to the core algorithm (utils.min.js)
CI/CD pipeline now injects licenses automatically after minification

Performance Improvements

• Improved border shorthand conversion eliminates redundant properties
• Enhanced outline shorthand handling removes default values
• Optimized background shorthand with comprehensive property consolidation
• Reduced boundingBox from 8 to 4 essential properties (x, y, width, height)

Metadata Enhancements

• Added userAgent to capture browser/OS information
• Added extension version dynamically from manifest

Store Compliance

• Added short_name field for better display in limited spaces
• Standardized manifest fields across Firefox and Chrome
• Ensured all field lengths comply with store requirements

Technical Details

• Estimated 20-30% additional JSON size reduction from property optimizations
• Border properties now use individual side shorthands when needed
• Background properties intelligently exclude default values
• All metadata changes result in smaller overall payload

Minor UI Changes
- Added Mozilla Add-ons review link to popup footer
- Improved user engagement with gentle star rating request
- Updated version display in popup interface

Bug Fixes

• Fixed memory leak from uncleaned interval timer that was causing crashes over time
• Fixed event listener accumulation across script injections that led to performance degradation
• Improved event listener cleanup using bound function references instead of unreliable boolean flags
• Enhanced cleanup sequence to prevent resource leaks on page navigation and tab switching

Technical Improvements

• Proper interval ID tracking with clearInterval on cleanup
• Bound event handler references for reliable listener removal
• Safer event listener management that works across multiple script injections
• Better resource disposal prevents memory accumulation during extended browsing sessions

Bug Fixes:

Fixed extension crashes after multiple uses that caused "something went wrong" errors. Resolved duplicate script injection that was causing memory leaks and accumulating event listeners. Fixed orphaned DOM elements that were
polluting pages. Improved error handling with graceful degradation when background script becomes unavailable.

Performance Improvements:

Added intelligent lifecycle management so background script hibernates when not in use. Wake-up occurs on demand with instant activation when user opens popup or clicks icon. Reduced memory footprint through better cleanup of
large DOM capture data. Optimized cleanup intervals to be less frequent but more targeted.

Technical Improvements:

Persistent state management ensures injection tracking survives background script restarts. Health monitoring provides automatic detection and recovery from background script issues. Fallback clipboard methods work even when
background script is unresponsive. Better event listener management prevents duplicate handlers and memory leaks.

Reliability:

Extension can hibernate naturally between uses making it Firefox-friendly. Instant wake-up when user interaction occurs. Maintains data persistence for "Copy Again" button functionality. Graceful handling of Firefox memory
management.
