Firefox about:config options

A small compendium of configuration options that can be used in Firefox to alter its behaviour

• Disable Proton: set browser.proton.enabled to false
  • Proton is the new-style UI introduced in Firefox 89.0.
• Re-enable compact mode: set browser.compactmode.show to true
• Stop websites preventing you from pasting: set dom.event.clipboardevents.enabled to false
  • This might break some websites if they rely on the ability to detect when you've pasted something.
• Disable the hardware media keys from play/pausing videos and other media inside of Firefox: set media.hardwaremediakeys.enabled to false
  • Useful if you mostly use the media keys for music in other apps like Spotify
