# 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
