Features & Capabilities

Video Frame Grid captures evenly-spaced frames from any video and displays them as a contact sheet. Quickly scan an entire video to decide if it's worth watching, or jump straight to the moment you're looking for.

HOW TO USE:

Click the extension icon and toggle it on for the current site
The page reloads and the grid appears next to or below the video
Click any thumbnail to seek the video to that timestamp
The grid auto-regenerates when you navigate to a new video

THREE VIEWS:

Side view — grid sits next to the video, matching its height
Below view — grid sits below the video in 3 columns
Floating view — draggable panel for sites with unusual layouts The extension picks the best view automatically, but you can switch anytime from the popup or the view-toggle button on the grid.

SMART CAPTURE:

iOS-style scroll-wheel picker for setting the frame interval (1-60 sec/min/hrs)
Uses requestVideoFrameCallback for accurate frame capture
Detects and re-captures duplicate frames
Customizable keyboard shortcut (default: Alt+G)

PRIVACY:

No data collection
No network requests
No tracking, no analytics
Stores only your preferences (enabled domains, interval) in local browser storage
Frame capture is done entirely in your browser using HTML5 Canvas

WORKS WITH: Standard HTML5 video, blob URLs, HLS/DASH streams (without DRM), YouTube (with SPA navigation handling), Vimeo, and most other video sites.

DOES NOT WORK WITH: DRM-protected video (Netflix, Disney+, Prime Video, Hulu) — browsers intentionally block canvas frame capture for these.

Is Video Frame Grid Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Video Frame Grid requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Video Frame Grid is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
