Default Quality Lock - Force 1080p HD for YouTube

Force YouTube to play the video quality you want — and keep it locked. Tired of YouTube starting videos at 480p, or dropping back to "Auto" on the very next clip? Default Quality Lock forces every YouTube video to play at the resolution YOU choose — 1080p, 1440p, 4K (2160p), 720p, and more — and keeps it locked, so you never open the quality menu again. IT ACTUALLY STICKS Most quality extensions set your resolution once and then quietly give up. Default Quality Lock keeps your setting locked through: • The next video and autoplay • Seeking and rewinding • Ads (your content locks the moment the ad ends) • YouTube's automatic downgrades • Even after the extension updates — no manual refresh needed BUILT TO KEEP WORKING It sets quality the fast, silent way using YouTube's own player. If YouTube ever changes how that works, it automatically falls back to driving the built-in quality menu for you — so it keeps working when other extensions break. WHAT YOU GET • Force 1080p HD as your default on every video • One-click lock for 4K (2160p), 1440p, 1080p, 720p, 480p, or 360p • "Highest available" mode for maximum resolution • Automatic fallback to the next-best option when a video doesn't offer your pick • Works on regular videos, Shorts, and embedded players • Remembers your choice across sessions and devices • A clean, single-setting popup — no clutter, no pop-ups PRIVATE BY DESIGN Your trust matters more than any feature: • Only the essentials: storage + YouTube access • No "tabs" permission — it can't see your browsing • No analytics, no tracking, no external requests • Zero data collected • Built on Manifest V3 HOW TO USE 1. Click the Default Quality Lock icon. 2. Pick your resolution. 3. Done — every YouTube video now plays locked to your setting. Note: on slower connections, forcing a very high resolution may cause more buffering — that's the trade-off of a fixed resolution. Pick the one that fits your connection.
