Build

1. Install base tools:

   • Node.js.
   • Yarn v1.

2. Run

   yarn install

3. Fill the src/_locales directory with localization files. Skip this step if they're alredy there. Either:

   • If you're using git:

     git submodule update --init

   • If you don't want to use git, download them from the translations branch and put in src/_locales manually.

4. • To build for Gecko (e.g. Firefox):

     yarn build:gecko

   • To build for Chromium (e.g. Chrome)

     yarn build:chromium

   Bundled files will appear in ./dist.

Then you can install it on the extensions management page of your browser (Chromium, Gecko).

Privacy & security

In short: it's fine.

As with practically every other extension, websites you're visiting may detect that you're using this (or alike) extension, and your settings for the extension, by observing:

• playback rate changes of an element.
• the fact that createMediaElementSource has been called for an element.
• increased frequency of media chunk requests resulting from increased playback rate. This cannot be mitigated with disabling JavaScript.
• the fact of requesting the same media twice, as a result of using the cloning algotihm.

However I doubt that currently there are services that do specifically this. But there may be.

Other than that, there are no known things concerning this.
