Extension summary

Use to control speed on HTML5 video and audio streams.

Can add SRT files as WEBVTT tracks, style the subtitles and set the delay so that they are in sync (tip: use the console log to help you) (Press the underscore button on the UI to start/complete the process of adding subtitles).

This extension is safe to use in incognito mode as the only data it stores is the settings; I recommend enabling it for file URLs.

You can add a colour matrix and other video CSS, but there is one enabled by default that makes greens and pinks more realistic.

Changelog: 15/10/2023: Picture-in-Picture button added to bar; more efficient code used to search for streams. 05/01/2023: Faster code used when searching for streams. 01/12/2022: Colour matrix added as a blob URL rather than by inserting a tag into the web page. 25/11/2022: No longer shows the native HTML5 video controls when playbackRate is changed. 24/10/2022: Improved element handling (e.g. searching for tags); better hiding of HTML elements other than the video hide controller now causes the extension name to be printed before the hiding status. 16/10/2022: Video controls will show up more often when toggling hide controller.
