Build

  1. Install base tools:

  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.

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

      yarn build:gecko

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

      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. It doesn't interact with third parties or try to do other creepy stuff.
