HurryUp by MattPlm

HurryUp is a small and simple firefox extension for displaying time in the youtube player according to the playback rate.

The addon allows displaying the current time, video duration and remaining time in the youtube player adjusted to the current playback rate.

⚠ Disclaimer: The current version is very experimental and still a work in progress. Don't expect this addon to work flawlessly until version 1.x is released.
I am working on fixing some issues that I have already identified and probably more edge cases that I haven't stumbled upon yet. If you find issues, don't hesitate to report them over on github @ https://github.com/mpaulmier/hurryup
