Brings GIFs back to the Tumblr dashboard instead of WEBPs

Features & Capabilities

GifsOnTumblr is a Chrome extension designed to bring back authentic animated GIFs on your Tumblr dashboard by preventing Tumblr's automatic conversion to WebP format. This helps maintain the original glitch art quality and makes saving GIFs easier. While Tumblr converts GIFs to WebPs, this extension tweaks the dashboard to serve the original GIFs instead, enhancing your browsing experience.

Please note that pages with many GIFs might load slower due to the nature of GIFs, and your browser might download both GIF and WebP formats. Visit the GitHub repository for more details and updates.

Is GifsOnTumblr 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.

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

Risk impact analysis details

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.

GifsOnTumblr has earned a fairly good reputation and likely can be trusted.
