Features & Capabilities

Click the toolbar button, then click any animated GIF, WebP, APNG, or AVIF and a compact player bar appears attached to it. From there you can pause, step through frames one at a time, scrub to any point, adjust playback speed, or flip the direction into reverse or ping-pong bounce.

Controls

Play / Pause
Step one frame back or forward
Scrub to any frame by clicking or dragging
Adjust playback speed
Change direction: forward, reverse, or bounce
Drag the player bar out of the way; double-click to snap it back
Keyboard shortcuts: Space to play/pause, arrow keys to step, Home/End to jump to the first or last frame

On a standalone image page (e.g. a direct .gif link), the controls appear the moment you click the toolbar button; image selection is automatic.

Privacy

Jiffy works entirely on your device. It doesn't collect data, make network requests, or track anything.

Is Jiffy 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.

Jiffy requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

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