Version 1.5:

• Added redundancy to ensure the extension loads

ℹ️ The code is in content-script.js and is heavily commented

The problem this solves:

The video/audio element is hidden and only referenced in spotify's encapsulated code

This solution:

• The code main part of the code is written in a template literal string with back quotes ---> `

  • This allows a multilined string with double quotes and single quotes without breaking the string variable

• This string named code is injected into the top of the html dom as a script element when the page loads

  • It loads before spotify's scripts and can pre-append the browser's code of document.createElement before it's used
  • Whenever spotify's scripts execute document.createElement('video') a reference to the element created is stored in VideoElementsMade
    • document.createElement('video') used to be an audio element until spotify started supporting videos and now it's randomly either

• The timeout() loop is just an added assurance that the playbackspeed input element is created and that the speed is changed to the stored speed from previous sessions

My previous solution(bad)

• made a full copy of spotify's code
  • forced having to block spotify's script with a firewall extension
  • slow to open with editor and prone to crashing when debugging
  • firewall made things inconsistent
  • doesnt ever update when spotify updates :(
• added window.spotifyContext = this; when you click play
  • this allowed window.spotifyContext._getTrackPlayer() from anywhere
