非常实用的插件，目前还没发现不兼容的网站

Hello,
Any chance of adding global shortcuts to Firefox, like the ones in Chrome?
The current shortcuts only work when you are on the active player page.
I love this extension.

it works great!

Good addon, simple to use

Other extension are laggy and buggy , I make a mozilla id just to review this extension . Very nite extension.
Great works like charm.

非常好扩展，使我的课程16倍速播放

Simple but really useful

Tried a few different speed extensions/addons (including userscripts), but settled on this one.
