Version 1.3.0 — Compatibility & Reliability

Important fix: The minimum supported Firefox version has been lowered from 140 to 109 (desktop) and from 142 to 120 (Android). If 1.2.0 wouldn't install or do anything on your version of Firefox, this update fixes that.

What's new:
• Now supports m.youtube.com and the bare youtube.com domain, not only www.youtube.com. Mobile and naked-domain users are now properly covered.
• New "loop seek-back" detector — catches the case where YouTube manages to loop a Short before our loop guard kicks in, and advances anyway.
• More reliable next-Short detection: dedicated checks for the "ended" event, near-end timeupdate, and surprise seek-to-start.
• Verified retries — the extension now checks that there's actually a next Short to advance to before retrying, instead of spamming events at the end of a feed.

What's improved:
• Replaced the 50ms loop-disable polling loop with a proper property override + targeted attribute observer. Lower CPU usage, harder for YouTube to fight.
• Throttled DOM-mutation handling to 250ms. YouTube mutates the DOM constantly; reacting to every change was wasteful.
• Fixed memory leaks where the timeupdate listener and loop-disable interval were never cleaned up between Shorts.
• Disabled debug logging by default (was accidentally left on in 1.2.0). You can re-enable it from the console with: window.__shortsAutoNextDebug = true

Bug fixes:
• Fixed a cleanup bug where moving between Shorts could leave stale event listeners attached.
• scrollIntoView now uses a value supported by older Firefox versions (the previous "instant" was silently ignored).
• Touch-event fallback is now feature-detected so it can't throw on desktop builds without touch APIs.
• Single-instance guard so the script can't accidentally run twice on the same page.

Privacy is unchanged: no data collected, no network requests, no tracking.

Fixed: Extension now works when navigating to Shorts from the YouTube homepage without requiring a page refresh. The extension will automatically activate when you click on any Short from anywhere on YouTube.

Technical improvement: Content script now loads on all YouTube pages to properly detect single-page application (SPA) navigation events.
