Version 1.0.1.13 — User-facing update summary

This update adds 1xBet support, improves sport-category detection, adds a new support shortcut, and fixes several display and tracking issues.

What’s new

Added support for 1xBet on supported 1xBet sites.
OddsGuard can now show comparison overlays on supported pre-match, live, and outright market pages where odds data is available.
Added a new Chat quick action in the popup, giving users a faster way to contact support when chat is enabled.

Improvements and fixes

Fixed an issue where submenu icons could disappear on some sportsbook pages.
Improved detection for broad sport categories like basketball, baseball, ice hockey, American football, and MMA, so category pages are no longer treated as only NBA, MLB, NHL, NFL, or UFC pages.
Improved MMA page detection across multiple supported sportsbooks.
Improved affiliate routing reliability for supported partner links.
Fixed an attribution issue affecting Everygame links.

Notes

1xBet overlay coverage depends on available odds data by sport. Soccer, baseball, and basketball are currently supported; additional sports coverage is still being expanded.

OddsGuard Firefox Extension – Release Notes

Summary of changes since last Firefox build (~1 month ago)
Current Firefox manifest version: 1.0.0.3

Security and AMO warnings
- Unsafe assignment to innerHTML:
  All dynamic HTML in the extension is now set via a single helper that sanitizes with DOMPurify before assigning to innerHTML. Overlay, badge, modal, and notification code paths use this helper so AMO’s “adequately sanitized” requirement is met.
  See FIREFOX-STORE-WARNINGS.md.
- Function constructor / eval:
  Documented that the warning comes from a bundled dependency (e.g. webpack runtime), not from application code; submission notes and mitigation options are in the same doc.
Cross-browser and compatibility
- Cross-browser support: Extension build and behaviour aligned for Chrome, Firefox, and Safari (MV3 where applicable, webextension-polyfill for Firefox/Safari).
- TypeScript and API usage: Improved type safety and cross-browser API usage in extension code.
Terminology and store compliance
- Responsible gaming: Added responsible gaming icons and related UI/links where appropriate.
New and updated bookmaker / provider support
- New adapters / regions: BetVictor, Unibet (multi-region), Grosvenor, BetMGM UK (Kambi), LeoVegas, William Hill, LiveScoreBet, BoyleSports, Coral, SkyBet, Ladbrokes.
- Fixes and improvements:
  Bet365 (3-way market detection, columnar layout handling), 888sport outrights, Betway outright overlays, LiveScoreBet 3-way and draw button placement, Plan D provider normalization, US Exchange region mapping, Kambi adapters and category bypass.
Overlay and modal behaviour
- Overlay clearing: Fixed overlay clearing bugs and consolidated container discovery and clear logic.
- Z-index: Overlay z-index and hover behaviour corrected so overlays stack and interact correctly.
- Event type and detection: Improvements to event type detection and overlay behaviour for different markets (e.g. outrights, 3-way).
- Modals: Compare All, Best Prices, and Detailed Comparison modals now share a single implementation in the modal-manager; duplicate logic and dead code in the overlay service have been removed.
