Twitter Extras

Introduces additional features and abilities to your Twitter experience. For example, easier saving of media (such as GIFs and Videos), as well as support for Picture-in-Picture (video pop-outs). Other options available in Options (click the ☰ icon next to the extension, select Options from list) include the ability to hide "Who to Follow" and "What's Happening" sidebar items, wrap tick-escaped inline code with <code> tags, make voice tweets downloadable, and convert video timestamps to clickable links.
