v1.9.9 — Firefox notification fix

• Fixed: notifications were not delivered on Firefox — "silent" property is unsupported by Firefox's notifications API and caused the entire notification to fail
• Fixed: channels that triggered the error were re-detected as new streams on every check cycle

v1.9.8 — Notification improvements + Firefox compatibility fixes

• Fixed: channels with null startedAt were not triggering notifications — extension now queries Kick API for stream start time and notifies if started within 10 minutes
• Fixed: new streams were incorrectly skipped as "pre-existing" in UTC+3 and similar timezones (missing Z suffix in Kick API created_at field)
• Fixed: newly followed channels that had been live for 10+ minutes triggered false notifications
• Fixed: anomaly badges were visible in popup even when anomaly detection was disabled
• Fixed: notification buttons (Open/Mute) caused errors on Firefox due to unsupported parameters
• Added: informational note in Options when using Extension sound mode on Firefox (system sound plays alongside extension sound)

v1.9.7 — Firefox fix + bug fixes

• Fixed: Background script was not starting on Firefox — manifest had "type": "module" conflicting with importScripts() in background.js
• Fixed: Removed data_collection_permissions field (Chrome-only, caused Firefox manifest warning)
• Fixed: Live notifications not firing for channels with null startedAt — extension now queries Kick API directly for stream start time
• Fixed: UTC timezone offset causing new streams to be skipped (affected UTC+3 and similar timezones)
• Fixed: False notifications when following a channel that has been live for 10+ minutes
• Fixed: Anomaly badges shown in popup even when anomaly detection is disabled
• Fixed: viewerHistory sync quota error — large data no longer written to cloud sync
• Fixed: Anomaly badge repositioned to end of note line
• Fixed: Test sound buttons were silent on Firefox
• Fixed: Auto-launch tab now opens in foreground for Cloudflare auto-verification

• Fixed: Removed data_collection_permissions field (Chrome-only, caused Firefox manifest warning)
• Fixed: Live notifications not firing for channels with null startedAt — extension now queries Kick API directly for stream start time
• Fixed: UTC timezone offset causing new streams to be skipped (affected UTC+3 and similar timezones)

• Fixed: Test sound buttons were silent on Firefox
• Fixed: Auto-launch tab now opens in foreground for Cloudflare auto-verification

v1.9.5 — Bug fixes

• Fixed: live notifications not firing for channels that return null startedAt from the Kick API — extension now queries the API directly for stream start time
• Fixed: UTC timezone offset causing new streams to be incorrectly classified as pre-existing (affected UTC+3 and similar timezones)
• Fixed: anomaly badges and notes appearing in popup even when anomaly detection is disabled
• Fixed: viewerHistory sync quota error — large viewer history data no longer synced to cloud storage
• Fixed: newly followed channels that are already live (10+ minutes) no longer trigger false notifications
• Fixed: anomaly badge repositioned to end of note line for cleaner card layout

v1.9.1 — Firefox test sound fix + Czech support + browser language auto-detection

• Fixed: Test sound buttons were silent on Firefox — audio now plays directly in popup context instead of background script (Firefox does not support AudioContext in service workers)
• New: Czech (cs) — 13th supported language
• New: Browser language auto-detection — extension matches browser UI language on first install; manual override available in Options

v1.9.0 — Czech language support + browser language auto-detection

New: Czech (cs) — 13th supported language, covering the largest previously unsupported user segment.

New: Browser language auto-detection — the extension now automatically uses the browser's UI language on first install or update. A toggle in Options lets users switch to manual language selection at any time. If the browser language is not supported, English is used as fallback.

v1.8.7 — Viewer anomaly system overhaul + sensitivity controls

New: Viewer drop detection — alerts when a live channel loses viewers abnormally fast. Configurable sensitivity (Sensitive / Balanced / Strict).

New: Viewer spike detection now uses rate-of-change (ROC) sliding window — detects sudden jumps at any point during a stream, not just after 15 minutes. History window extended from 4 minutes to 30 minutes (60 data points).

New: streamPeak / streamValley tracking — peak and valley are tracked across the entire stream session, enabling accurate long-term anomaly detection. Resets after each cooldown period so every "chapter" of a stream is evaluated independently.

New: Sensitivity bar (Sensitive / Balanced / Strict) for both spike and drop detection, with individual on/off toggles. All settings buttons standardized to the same visual style.

Fixed: duplicate notifications (2–3 per channel) when the browser starts with live streams already running.

The root cause was three separate startup triggers (onInstalled, onStartup, alarm fallback) firing simultaneously, each independently calling the channel check. A storage-based initialization lock and corrected first-run logic now prevent this.

No features changed.
