Ultimate Browser Assistant 제작자: Sakib

Ultimate Browser Assistant is a lightweight Firefox/Zen extension with three focused tools:

🔍 Hover Zoom
Hover any image, GIF, video, or CSS background to see it at true actual size — no more squinting at tiny thumbnails. Works on Google Images (shows the real full-resolution photo, not the thumbnail), and includes a Shift+hover "quick look" shortcut for an instant full-view with a download button. Fully customizable: trigger mode (hover / Alt-hover / Ctrl-hover), preview size, follow-cursor or anchored, hover delay, and auto-hide after 5s.

⬇ Smart Downloads
One-click download button on any previewed media. Recent downloads list, completion sound, and folder notifications — all from the popup, no extra clicks.

▶ Social Video Controller
Adds a clean time pill and (when the page doesn't already have one) a draggable progress bar to Reels/Shorts-style videos on YouTube, Facebook, Instagram, X/Twitter, Reddit, TikTok, and more — toggle per platform.

Everything is controllable per-site, takes effect instantly, and respects your privacy: no data collection, no tracking.
