User reviews

Global Speed is praised for its effective and versatile video speed control across many streaming platforms and regular updates. Users appreciate customizable shortcuts and added visual features. However, recurring issues include occasional malfunctions requiring reinstall, incompatibilities with some websites, fullscreen mode problems, and missing advanced features. The developer actively maintains the extension, and users generally find it reliable and valuable despite minor bugs.

Pros

Offers customizable shortcut keys for video speed control, enhancing user experience.
Regularly updated and maintained by the developer.
Supports additional features like video brightness adjustment and picture-in-picture control.

Cons

Occasionally speed control fails and requires reinstalling the extension.
Does not work properly on certain websites (e.g., WhatsApp Web, Douyin, Looptube.io) and sometimes fails in fullscreen mode.
Some users experience bugs like media list disappearance or conflicts causing video to show black screen with other extensions.
Lack of some requested features like more flexible audio reversing controls, loop toggle shortcut, or site-specific speed settings.

很好用，但是偶尔会发现调节了速度，但却无法变速的状况，需要卸载重新安装，请问有办法解决这个bug吗？

Hi, just tweaking around, any way to run shortcuts from another tab (e.g. google), to the currently playing video, without affecting other video tabs?
