	===Mandatory add-on signing (2016)===		===Mandatory add-on signing (2016)===
	In 2015, Mozilla introduced extension signing (add-on signing) to Firefox, meaning the browser would show a warning if the user ran an extension not approved by Mozilla. This was later expanded to block the extension, but the user was able to override it by modifying an <code>about:config</code> property. In 2016, Mozilla took that option away as well.		In 2015, Mozilla introduced extension signing (add-on signing) to Firefox, meaning the browser would show a warning if the user ran an extension not approved by Mozilla. This was later expanded to block the extension, but the user was able to override it by modifying an <code>about:config</code> property. In 2016, Mozilla took that option away as well. This means Mozilla is able to remotely disable extensions, removing ownership from the end user.

	Shortly after extension signing was announced, the user base already responded negatively, stating how this would limit the freedom of power users.<ref>[Introducing Extension Signing: A Safer Add-on Experience \| Mozilla Add-ons Community Blog https://archive.today/2024.01.22-024009/https://blog.mozilla.org/addons/2015/02/10/extension-signing-safer-experience/]</ref>		Shortly after extension signing was announced, the user base already responded negatively, stating how this would limit the freedom of power users.<ref>[Introducing Extension Signing: A Safer Add-on Experience \| Mozilla Add-ons Community Blog https://archive.today/2024.01.22-024009/https://blog.mozilla.org/addons/2015/02/10/extension-signing-safer-experience/]</ref>
