Online Dictionary Helper Revival by Howyeaherrr

Note: This is a fork of the original "Online Dictionary Helper" project, updated with new features and optimizations by a new maintainer.

Online Dictionary Helper translates words and phrases while you read webpages. Simply hover or select text to see definitions with context sentences, and send them to your local Anki for spaced repetition.

New Features in this Fork:
- Android Firefox Support: Fully adapted and fixed compatibility issues for Firefox on Android.
- Dark Theme: Supports "Follow System / Light / Dark" modes with an inversion filter to optimize hardcoded styles.
- Site Rules: Domain-specific overrides for dictionaries, Anki decks, and word limits with Cloud Sync support.
- Custom AnkiConnect URL: Allows custom IP/Port configuration to connect to LAN or remote Anki servers.
- Anki Feedback & Duplicate Hints: Real-time Toast notifications for card creation with automatic duplicate count alerts.
- Recent Cards List: View and manage the last 5 added Anki cards directly in the popup with one-click deletion.
- Selection Word Limit: Configurable limit for text selection with CJK-aware counting to prevent browser lag.
- Smart Language Matching: Automatically detects language and matches dictionaries, supporting non-standard scripts.
- Performance Optimization: Implements event throttling and LRU cache for audio to enhance stability and prevent leaks.
- Bug Fixes: Resolved hotkey conflicts in editors, text boundary detection errors, and popup scrolling jitter.
