YouTube Toolkit for Firefox 作者： Strade

Volume drag, layout trimmer, auto Jump Ahead, and 2x speed lock — essential YouTube tools, each with its own toggle.

A few simple tools for watching YouTube.

• Volume: drag sideways on the video to turn volume up or down.
• Speed: hold left-click and release over the 2x icon to lock 2x speed (or reset to 1x).
• Layout: make the page narrower so it isn’t stretched across a huge screen.
• Skip: after one skip, it clicks YouTube’s own “Jump ahead” button for you.

Turn any of them off if you don’t want it. Nothing is sent to a server.
