Custom Video Speed for YouTube™ 作成者: Thomas Povinelli

7.1.0 BUG FIX UPDATE!
Fixed an issue where a user could not save their options on the preferences page. Also getting ready for manifest v3. This should not affect the users of the extension at all, but manifest v3 is the next version of the WebExtensions API and will be current for Firefox soon.

7.0.0 Update!
The extension will now ignore your key presses if you are typing in a text box! You can finally write comments with punctuation without having it mess with your speed settings. You can turn on the old behavior if you would like in the options page.

6.1.3 Update!
Changed name and description to comply with Google's guidelines

6.1.2 UPDATE!
Changed icon to comply with guidelines

6.1.1 UPDATE!
Replaced Icon due to guidelines

6.1.0 UPDATE!
Contributions from @jclaveau on GitHub to enable features in embedded YouTube™s and iframes from YouTube™.

6.0.0 UPDATE!

This is a breaking change. In an effort to make the extension work as closely as possible to how it was in 5.1.0 provided no options are changed, the following things were done
1. 'keypress' was changed to 'keydown' this due to how macOS reports codes in keypress. This should be transparent to the users
2. The options page no longer uses `keyCode` it now uses `key`. `keyCode` is deprecated and inconsistent between platforms and more opaque to use.
3. `event.preventDefault()` is now an option and no longer forced on. Not calling preventDefault() is the old behavior of 5.1.0 so this decision is so that the extension more closely works like 5.1.0 if no key bindings are changed

This will make the extension act more like it did before 5.2.0. It does however break the keyboard shortcuts that people might have set until now


5.2.0 UPDATE!

NEW FEATURE: Change the keyboard shortcuts for the app! You can now change the keys that control the extension. Below (in the description) you can see the default keys used to control the extension. You can use the new options page to change which keys do what. There is also (though there has been for a while) the option to disable keyboard controls entirely if you prefer.

RECENTLY UPDATED!!! BUGS FIXED!! I noticed that when ads play it resets the speed the video. I have added a mechanism that ensures the speed is always moving at the current setting when the video is playing even after an ad interrupts it!!

This extension lets you change the speed of YouTube™ videos in a more granular way than the default options in the player. The player on YouTube let's you change the speed to 0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 1.75x, and 2.0x the normal speed. This extension lets you change the speed of playback to between 0.1x to 8.0x normal speed by steps of 1.0, 0.5, 0.1, or 0.05.

Once you find a speed you like, you can also save it as the default speed which all YouTube™ videos will play at when opening.

You can also program up to 7 "preset speeds" that allow you to simply click a button and set the speed of the YouTube™ video to your stored preset.

By default this extension adds a the ability to control the speed of a YouTube™ video and some playback with keyboard shortcuts.

The '+' and '-' keys to change the speed by 0.1 and to the '*' and '/' keys change the speed in increments of 1.0.

If you hold shift while pressing these, '+' and '-' move in steps of 0.05 and '*' and '/' move in steps of 0.5.

It also assigns '`' to reset the speed to 1.0x normal speed.

Finally, it uses '[' and ']' to move through the video in time steps proportional to the speed of the video, rather than in increments of 5 or 10 seconds.

These shortcuts *can* be disabled on demand if you prefer not to have them and can be re-enabled at any time

I made this extension for fun and because it really made my YouTube experience better. I published it because I thought it might be useful for other people as well. I cannot promise every single YouTube™ page and video will work perfectly with this extension. YouTube™ has a lot of places like gaming, educational playlists, livestreams, etc.

This extension is open source on GitHub (see website) link, and I am open to suggestions, issues, and fixes but I cannot make any promises about what I will do with those things if i receive them.
