 # Changelog
 
+## Version 3.1.8
+
+### Support + Backups
+
+- Added a new Support page in the dashboard with Ko-fi embed.
+- Auto-backups now overwrite a single rolling file: `Downloads/FilterTube Backup/FilterTube-Backup-Latest.json`.
+- Auto-backup download URL handling is now cross-browser:
+  - Uses Blob URLs when available.
+  - Falls back to `data:` URLs in Chrome MV3 service worker contexts where `URL.createObjectURL` is unavailable.
+
+### Fixes
+
+- Fixed auto-backup failures in Chrome caused by `URL.createObjectURL is not a function`.
+- Fixed download failures in Firefox caused by `data:` URL download restrictions.

 FilterTube uses a robust hybrid blocking mechanism for YouTube Shorts.
 
-**Current behavior (v3.1.7):** Shorts blocking is often **near-instant** because FilterTube learns `videoId → UC...` mappings from intercepted YouTube JSON and persists them. This makes Shorts behave much more like regular videos on Home/Search.

 ## Executive Summary
 
-FilterTube v3.1.7 implements a robust **Hybrid Filtering Architecture** that combines preemptive **Data Interception (Main World)** with a resilient **DOM Fallback (Isolated World)**. This dual-layer approach ensures comprehensive content filtering across all YouTube surfaces (Home, Search, Watch, Shorts) while maintaining high performance and a "Zero Flash" user experience when YouTube routes content through JSON.

+## Cross-browser Downloads (Export + Auto-backup)

+FilterTube writes JSON files using the browser `downloads` API.

+*   **Blob URL path**: when `URL.createObjectURL` is available, FilterTube generates a Blob URL so downloads work in Firefox (which blocks `data:` URL downloads).
