## Description

Frame Timer Extension is an addon that allows you to quickly and accurately calculate the time between 2 frames in a YouTube video. This tool is made for retiming speedruns.

This extension works the exact same way as the original <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3cfc2c878455d716c2478ad6a25461b5555cf6b42010d65a2eaea5a4a80d622f/https%3A//slashinfty.github.io/yt-frame-timer/" rel="nofollow">yt-frame-timer</a>, but with a few improvements such as:
- Buttons to automatically set the start time, end time and frame rate.
- Always with you and no extra tabs needed.
- Easily jump a specific number of frames forward or backward with a button click.
- YouTube keyboard controls (such as arrow keys) are supported.
- Easily set the playback speed of the video
